Chapter 2, Problem 2.78P
Interpretation Introduction

Interpretation:

The information about the relative number of ions and the mass percent of each element in the formula MgF2 is to be determined.

Concept introduction:

Law of definite composition – The law of definite compositions was introduced by Joseph Proust. This law states that a particular compound is composed of the elements in the exact same proportions, irrespective of the source.

The formula to calculate the mass fraction of an element in a compound is,

Mass Fraction=[(Number of atoms of the element in the compound)(Molar mass of the element)Molecular mass of the compound] (1)

The formula to determined the mass percent of an element in a compound is,

Mass Percent=(Mass Fraction)(100) (2)
