Answer:
8,95
Explanation:
Density is equal to mass/volume
[tex]D=\frac{m}{v} \\D= \frac{1668g}{186.2} \\D = \frac{8,95g}{cm^3} \\[/tex]
approximately

Did you knew that is because of his low density that ships can fluctuate?
Despite their big mass, their volume are far greatter, so the Buoyancy Force acts heavily on them.
What is the mass of an object with a density of 0.3456 g/cm3and a volume of 112.4 cm3?
Answer:
The answer is
38.85 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volumeFrom the question
density = 0.3456 g/cm³
volume = 112.4 cm³
The mass of the object is
mass = 0.3456 × 112.4 = 38.84544
We have the final answer as
38.85 gHope this helps you

What is the volume of the rock?
Answer:
8 mL
Explanation:
You read volume on a graduated cylinder by counting the number under the line on top of the liquid (minuscus).
Before the rock was added, the volume is 10 mL. After the rock was added, the volume is 18 mL. Subtract the two volumes to find the volume of the rock.
18 mL - 10 mL = 8 mL
How do you view failure? Is failure the end, or is failure an important lesson and motivator?
Answer:
Failure is a lesson
Explanation:
Without failure, we'd be less capable of compassion, empathy, kindness, and great achievement. It's through failure that we learn the greatest lessons that life could teach us.
What is a major difference between Animalia and Plantae kingdoms?

Which of the following is true about lava and magma? A Lava and magma are both types of molten rock. B Magma uses waves to break down lava over time. C When magma cools and hardens it becomes lava. D Magma is called lava when it’s below the Earth’s surface.
Answer:
a
Explanation:
magma is lava and lava is magma
A Lava and magma are both types of molten rock is true about lava and magma. Therefore, option A is correct.
What do you mean by molten rock ?Extrusive igneous rocks are formed when molten rock cools on Earth's surface. Rhyolite, pumice, and basalt are a few examples. Intrusive igneous rocks are formed when molten rock cools within Earth. Granite and gabbro are two examples.
Magma is an extremely hot liquid and semi-liquid rock found beneath the Earth's surface. The inner core, outer core, mantle, and crust make up Earth's layered structure. Magma makes up a large portion of the planet's mantle. This magma has the potential to push through holes or cracks in the crust, resulting in a volcanic eruption.
Scientists refer to molten rock underground as magma, and molten rock that breaks through the Earth's surface as lava.
Thus, option A is correct.

Where is the genetic material located in plant and animal cells?
A.in the lysosomes
B.in the nucleus
C.on the cell wall
D.inside the chloroplasts
HELP ASAP
Answer:
The genetic material of plant and animal cells is located in the nucleus (option B).
Explanation:
In living beings the nucleus of each cell contains the genetic information in a molecule called DNA. The DNA is formed by chains of nucleotides, whose order and sequence determine this information.
A DNA molecule forms a chromosome, and this contains genes, corresponding to segments or fractions of the DNA molecule that forms it. This information, contained in the nucleus, is necessary for the construction and functioning of each living being.
Lysosomes , cell wall and chloroplasts are other cellular structures that do not store genetic material.
Answer:
in the nucleus so b is the answer.

I will give Brainliest ...What mass of KBr is present in 75.0 mL of 0.250 M KBr solution?
Answer:
Mass of KBr present = 2.23 g
Explanation:
Number of moles of KBr present in 75.0 ml of 0.250 M solution of KBr is first determined
From the formula: molarity = number of moles/ volume (L);
Number of moles = molarity * volume (L)
Volume of solution in Litres = 75/1000 = 0.075
Number of mole = 0.250 * 0075 = 0.01875 moles
Mass = number of moles * molar mass
Molar mass of KBr = 119 g/mol
Mass = 0.01875 moles * 119 g/mol = 2.23 g

I’m positive that its 4 or 3 or maybe 5?? idk
Answer:
Option c is correct = 4
Explanation:
Significant figures:
All non-zero digits are consider significant figures like 1, 2, 3, 4, 5, 6, 7, 8, 9.
Leading zeros are not consider as a significant figures. e.g. 0.03 in this number only one significant figure present which is 3.
Zero between the non zero digits are consider significant like 104 consist of three significant figures.
The zeros at the right side e.g 2400 are also significant. There are four significant figures are present.
In given measurement 0.04350 there are four significant number

A mixture of iron and sulfur can be separated by attracting the Iron particles with a magnet. If the iron and sulfur mixture is heated strongly, iron (II) sulfide forms, which is no longer magnetic and cannot be separated by
physical methods. What is Iron (II) sulfide?
A heterogeneous mixture
B. compound
C. homogeneous mixture
D. element
Answer:B
Explanation: It is a compound
Iron (II) sulfide can not be separated by physical methods because it is a compound.
A compound is a combination of elements that are chemically combined. The components of a compound can not be separated by physical methods.
A compound is formed during a chemical change so it is not easy to reverse the process and obtain the constituent elements again.
Therefore, the components of Iron (II) sulfide can not easily be obtained again because a compound has been formed.
