The term "total moles of a solute contained in a kilogram of a solvent" is used to describe molality. Molal concentration is another name for molality. It is a measurement of a solution's solute concentration.
What is the molarity unit?Molarity is a unit of measurement for the concentration of a material in a specific volume of solution (M). The amount of a solute in one liter of solution is known as its molarity. The molarity of a solution is sometimes referred to as its molar concentration.
As a result, we start by assuming that the reaction is finished and that its volume is constant.
The following is the balanced stoichiometric equation:
BaSO4 + 2NH4(CH3COO) = Ba(CH3COO)2 + (NH4)2SO4.
First, we must identify the surplus reactant and the one that the process has entirely consumed.
For Ba(CH3COO)2,
The formula for moles is (Mass/) (Molar Mass)
Mass of barium acetate is 2.68 g.
Molar mass of barium acetate is 255.43 g/mol.
There are 0.0104 moles, or (2.68/255.43), in total.
Number of moles for (NH4)2SO4 = (Concentration in mol/L) (Volume in L)
Ammonium surface concentration in mol/L is 45 M.
(300/1000) x volume in L = 0.3 L
45 divided by 0.3 to equal 13.5 moles.
According to the reaction's stoichiometric balance, 1 mole of Ba(CH3COO)2 produces 1 mole of (NH4)2SO4.
Ba(CH3COO)2 produces 2 moles of NH4(CH3COO) from 1 mole.
Ba(CH3COO)2 will provide 2 0.0591 moles of NH4(CH3COO), or 0.1182 moles of NH4(CH3COO), from 0.0591 moles of Ba(CH3COO)2.
If NH4(CH3COO) has a molarity, give the number of moles. Volume in L
0.1182 moles are the number of moles.
0.3 L is equal to L of the solution.
NH4(CH3COO) has a molarity of (0.01182/0.3) = 0.0394 M.
Consider that 0.0394 M of NH4(CH3COO) likewise contains 0.0394 M of acetate ion because 1 mole of NH4(CH3COO) includes 1 mole of acetate ion.

How many moles of magnesium is 5.01 x 10^22 atoms of magnesium?
The question requires us to calculate the number of moles that corresponds to 5.01 x 10^22 atoms of magnesium.
To solve this question, we'll need to use the Avogadro constant. This number, defined as 6.02 x 10^23, relates the number of constituent particles (molecules, atoms or ions, for example) in a sample with the amount of substance in that sample. We can use it by saying that 1 mol of a substance corresponds to 6.02 x 10^23 constituent particles of this substance.
Then, using the information above, we can calculate the number of moles in 5.01 x 10^22 atoms of magnesium (Mg):
6.02 x 10^23 atoms of Mg --------------- 1 mol of Mg
5.01 x 10^22 atoms of Mg ---------------- x
Solving for x, we'll have:
[tex]x=\frac{(5.01\times10^{22}\text{ atoms of Mg)}\times(1\text{ mol of Mg)}}{(6.02\times10^{23}\text{ atoms of Mg)}}=0.0832\text{ mol of Mg}[/tex]Therefore, 5.01 x 10^22 atoms of magnesium corresponds to 0.0832 mol of this element.

When copper is heated with an excess of sulfur, copper(I) sulfide is formed.
In a given experiment, 1.53 g of copper was heated with excess sulfur to yield 1.76 g of copper(I) sulfide.
What is the percent yield?
If 1.53 g of copper is heated with excess sulfur to yield 1.76 g of copper (I) sulfide, the percent yield would be 75.43%.
Percent yieldThe percent yield of a reaction is the actual yield relative to the theoretical yield of the same reaction.
The percent yield of a reaction is mathematically expressed as:
Percent yield = actual yield/theoretical yield x 100%.
Let us now consider the reaction in question. The equation of the reaction is given as:
[tex]Cu + S --- > CuS[/tex]
The mole ratio of the copper that reacts to the copper sulfide that is formed is 1:1.
Recall that: mole = mass/molar mass
The molar weight of copper is 63.55 g/mol
Mole of 1.53 g copper = 1.53/63.55
= 0.024 moles
The equivalent mole of copper sulfide produced will also be 0.024 moles.
The molar mass of CuS is 95.61 g/mol
Mass of 0.024 moles CuS = 0.024 x 96.61
= 2.32 g
2.32 g is the theoretical yield of the reaction. But 1.76 g of copper sulfide is the actual yield.
Percent yield = 1.75/2.32 x 100%
= 75.43%
Thus, the percent yield of the reaction, if 1.53 g of copper is heated with excess sulfur to produce 1.76 g of copper (I) sulfide, is 75.43%.

During the chlorination of silicon, chlorine gas is reacted with solid silicon to form silicon tetrachloride.Si(s) + 2Cl2(g) + heat - SiC|4(g)Which will not cause the reaction to shift towards the products?A) adding a catalystB) increasing the pressureC increasing the temperatureD) increasing the concentration of CL2(g)
Let's analyze each option to find what best fit as an answer:
A - the function of a catalyst is to lower the energy of activation in a reaction, causing it to occur in a faster way. Since this question is not much about energy or kinetics, this would be the best fit, adding a catalyst or not adding it would not be too influential in the shift of the reaction.
B - Increasing the pressure in a reaction containing gases will mostly favor the side with a lower value of moles, smaller amount of moles = less pressure, so if we add more pressure, the reaction will shift towards the side of the products
C - If we treat heat as a reactant, if we add more temperature, it will shift towards the products, to counteract this increase of temperature
D - Adding reactants will favor the reaction to shift towards the products
Therefore the answer is letter A
7. The average human can hold 4.0 L of oxygen (O₂) in their lungs. At body temperature (37 °C) and 110 kPa, how manymoles of gas is that?
Answer

Find the element that is oxidized and the one that is reduced Si + 2 F2 --> SiF4
Answer
The element that is oxidized is Si and the one that is reduced is F₂.
Explanation
Si + 2F₂ → SiF₄
The given reaction is an oxidation-reduction (redox) reaction:
Oxidation: Si → Si⁴⁺ + 4e⁻
Reduction: 2F₂ + 4e⁻ → 4F⁻
Si is a reducing agent, and F₂ is an oxidizing agent.
An oxidizing agent gains electrons and is reduced in a chemical reaction.
A reducing agent loses electrons and is oxidized in a chemical reaction.
Therefore, the element that is oxidized is Si and the one that is reduced is F₂.
How many protons and neutrons are in an atom of Pm-147 ?
Promethium is the 61st element that you can find in the periodic table and the number 147 indicates the atomic mass.
Remember that the atomic number (in this case, 61) represents the number of protons, so there are 61 protons in Pm-147.
And to find the number of neutrons, we have to subtract the atomic number (61) from the atomic mass (147):
[tex]\#\text{ neutrons = 147-61 = 86.}[/tex]So, the final answer is that we have 61 protons and 86 neutrons of Pm-147.
Calculate the shortest wavelength of light capable of dissociating the Cl–Cl bond in one molecule of chlorine if the bond energy, or bond dissociation energy, is 243 kJ/mol .
The shortest wavelength of light capable of dissociating the Cl–Cl bond in one molecule of chlorine is 493 nanometer.
The formula to calculate Energy is given as follows :
E = BE / Na
E = energy
BE = bond energy = 243 KJ / mol
Na = Avogadro number = 6.02 × 10²³
substituting the values in the formula:
E = 243 × 10³ / 6.02 × 10²³
E = 4.03 × 10⁻¹⁹ J
By using Einstein equation for photon , we can calculate the shortest wavelength :
E = (h c) / λ
E = energy
h = Planck constant = 6.626 × 10⁻³⁴ J.s
c = speed of light = 3 × 10⁸ m/s
λ = wavelength
therefore,
λ = (hc )/ E
λ =( 6.626 × 10⁻³⁴ J.s × 3 × 10⁸ m/s ) / 4.03 × 10⁻¹⁹ J
λ = 4.93 × 10⁻⁷ m
λ = 493 × 10 ⁻⁹ m
1 nm = 1 × 10 ⁻⁹ m
Shortest wavelength = 493 nanometer.
