What is the relationship between layering of fluids and density?
Olin [163]

Density of a liquid determines how it will layer (heaviest to lightest). If the liquid is least dense it will float to the bottom. Layers will remain separated because each liquid is actually floating on top of the more dense liquid beneath it.

if an unknown sample solution is prepared by diluting 10.00 ml of the original solution to a total volume of 100.0 ml with deion
Usimov [2.4K]

The dilution factor of the unknown sample is 10. The dilution factor of a solution refers to the ratio of the final volume of the now diluted solution to the initial volume of the of the initial concentrated solution.

Mathematically;

The dilution factor is given by the formula;

Dilution factor = Final volume of the now diluted solution/ Initial volume of more concentrated solution

Final volume of the now diluted solution = 100.0 ml

Initial volume of more concentrated solution = 10.00 ml

Dilution factor = 100.0 ml/10.00 ml

Dilution factor =  10

A sample of water contains 5.24 x 1022 molecules. How many moles are in this sample?
LekaFEV [45]

Answer:

0.087 moles of water

Explanation:

Given data:

Number of molecules of water = 5.24×10²² molecules

Number of moles of water = ?

Solution:

Avogadro number:

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.  The number 6.022 × 10²³ is called Avogadro number.

1 mole = 6.022 × 10²³ molecules of water

5.24×10²² molecules × 1 mol / 6.022 × 10²³ molecules

0.87×10⁻¹ mol

0.087 mol
