The relative atomic mass of the given element is 40.372 amu.
What is relative atomic mass?The relative atomic mass of an element is considered as the sum of the isotopes masses each multiplied by the percentage which is found in nature.
The formula which is used to calculate the relative atomic mass is
Relative atomic mass = sum of all atomic masses of isotopes × fractional abundance
Given,
Mass of isotopes 1 = 19.19 amu
Mass of isotopes 2 = 20.99 amu
Mass of isotopes 3 = 21.99 amu
Fractional abundance of isotope 1 = 0.9092
Fractional abundance of isotope 2 = 0.0025
Fractional abundance of isotope 3 = 0.0883
By substituting all the values, we get
[( 19.19 × 0.9092) + (20.99 × 0.0025) + (21.99 × 0.883)]
= 17.447 + 0.052 + 22.873
= 40.372 amu.
Thus, we concluded that the relative atomic mass of the given element is 40.372 amu.

How many atoms are in 275 grams of iron (III) hydroxide. Include units and name of atom/molecule.
To calculate the number of atoms of any compound it is necessary to use the Avogadro constant. This is a constant of proportion between the amount of matter and the number of entities that are linked to that amount. These entities can be atoms, molecules, ions, electrons, protons, neutrons. The value of the Avogrado constant is 6.022 x 10^23 mol^-1.
So to calculate the number of atoms in 275 grams of iron (III) hydroxide:
- First you need to transform grams into moles
- transform moles into atoms/molecule using Avogrado constant.
- To transform 275 grams of Fe(OH)₃ you need to use the molecular mass of Fe(OH)₃ and the following equation: mole = mass/molar mass
Molecular mass of Fe(OH)₃:
Fe - 55.85
O - 16
H - 1
(1x55.85) + (3x16) + (3x1) = 106.86 g/mol
Replace the value in the equation:
mole = 250/106.86
mole = 2.34 mole of Fe(OH)₃
- Now, let's solve the number of molecules of Fe(OH)₃ into 2.34 mole of Fe(OH)₃:
6.022 x 10^23 molecule --- 1 mol
x molecule ---- 2.34 mole
x = 1.41 x 10^24 molecules of Fe(OH)₃
Answer: There are 1.41 x 10^24 molecules of Fe(OH)₃

Please help me to find yield of Alcl3 in gram
Theoretical yield is calculated based on the stoichiometry of the chemical equation. First, we have to find the number of moles of each reactant using the molar mass of each of them. You can find the molar mass using the periodic table: the molar mass of aluminum (Al) is 26.98 g/mol and the molar mass of chlorine gas (Cl2) is 70.8 g/mol:
[tex]34.0\text{ g Al}\cdot\frac{1\text{ mol Al}}{26.98\text{ g Al}}=1.26\text{ moles Al.}[/tex][tex]39.0gCl_2\cdot\frac{1\text{ mol }Cl_2}{70.8\text{ g }Cl_2}=0.551\text{ moles }Cl_2.[/tex]The next step is to find how many moles of AlCl3 are produced by each reactant. You can see that in the chemical equation, 2 moles of Al produces 2 moles of AlCl3:
[tex]1.26\text{ moles Al}\cdot\frac{2molesAlCl_3}{2\text{ moles Al}}=1.26molesAlCl_3.[/tex]And 3 moles of Cl2 produces 2 moles of AlCl3:

For this value, we have to find its mass using the molar mass of AlCl3 which is 133.2 g/mol:

Write down a specific step by step procedure of the titration process which the goal is to determine the unknown concentration of a basic solution.
Explanation:
Titration is a technique used to determine the amount of matter in a sample using a solution of known concentration. In other words, titration is a quantitative chemical analysis. In this process, the sample has its concentration determined through a chemical reaction when it is mixed with another substance. The use of pH indicators in this process is useful to determine the endpoint of the titration, indicating that the entire sample has reacted. Titration is used to accurately determine the amount of a substance, confirm that the concentration described on the label is true or that the amount of a chemical compound is indicated on the package.
Sample weighing: With the solid sample on a watch glass, weigh it on the balance.
Sample dissolution: The sample is transferred to an Erlenmeyer flask with water, where dissolution takes place.
Problem solution: The solution is transferred to a volumetric flask and the volume is made up with water, creating the problem solution.
Aliquot transfer: Remove an aliquot of the problem solution with the aid of a pipette and transfer it to an Erlenmeyer flask.
Titration: To the Erlenmeyer flask, the problem solution (titrated) is added and the solution of known concentration (titrant) is inserted into the burette.
An acid-base indicator is also added to the titrator to indicate when the titration should be stopped due to the color change. The color change indicates the end point or turning point of the titration.
After that, when the color change persists, the volume of titrant used is verified and stoichiometric calculations will help us to discover the concentration of the titrated solution.

Hydrogen bonding is formed when the partial negative charge at one end of a water molecule is attracted to the partial positive charge of another water molecule
Hydrogen bonding is a potent intermolecular force. In a water molecule, a partial negative charge is formed due to the oxygen, which is electro-negative.This oxygen gets attracted towards the positively charged Hydrogen, thus partial charges are shared between these two atoms of two different molecules.An electrostatic force is created between these molecules which helps in attraction of the partial charges.A hydrogen bond is formed between the water molecules which is formed due to hydrogen bonding. This kind of bond is formed between hydrogen atom and an electronegative atom, typically fluorine (F), nitrogen (N), or oxygen (O).Thus, when the partial negative charge at one end of a water molecule is attracted to the partial positive charge of another water molecule, hydrogen bonding is formed.
