Answer:

The correct answer is: PCl₃ and PCl₅

Explanation:

Law of multiple proportions, also known as the Dalton's Law, states that the when the two different chemical elements combine in order to form two or more than two chemical compounds, then the ratio of mass of the chemical element that combines with the fixed mass of other chemical element is the ratio of small whole numbers.

Example: PCl₃ and PCl₅

What is the molarity when water is added to 4 moles of sodium chloride to make 0.5 liter of solution?
loris [4]
       If    0.5 L of solution contains 4 mol
then let     1 L of solution contain  x  mol
      
       ⇒    (0.5 L) x  = (4 mol) (1 L)

                         x  = (4 mol · L)  ÷  (0.5 L)

                         x  = 8 mol

Thus the molarity of the Sodium Chloride solution is 8 mol / L   OR  8 mol/dm³.

How are the terms molar mass and atomic mass different from one another
Ronch [10]

1.Molar mass is the mass of one mole per single element while atomic mass is the mass of an atom at rest or is the number of protons and neutrons.

2.Molar mass is measured in grams per mole while atomic mass is “unitless.”

3.Atomic mass is measured via mass spectrometry while molar mass is computed via atomic weight.
