Chapter 2, Problem 2.19P

Interpretation Introduction

Interpretation:The mass percent of $\text{Ca}$ in dolomite is to be calculated. Also, based on only mass percent of $\text{Ca}$ , among dolomite and fluorite, the richer source of $\text{Ca}$ should be determined.

Concept introduction:Mass fraction of an element in a compound is determined by ratio of total mass of the element in that compound by total mass of that compound. Mass percent of an element is calculated from its mass fraction value by multiplication of mass fraction value of that element with $100$ .

The formula to calculate the mass fraction of an element is as follows:

  $\text{Mass}\text{fraction}\text{of}\text{an}\text{element}=\frac{\text{Total}\text{mass}\text{of}\text{that}\text{element}\text{in}\text{that}\text{compound}}{\text{Total}\text{mass}\text{of}\text{that}\text{compound}}$

Formula to calculate the mass percent of an element is as follows:

  $\text{Mass}\text{percent}\text{of}\text{an}\text{element}=\left(\text{Mass}\text{fraction}\text{of}\text{that}\text{element}\text{in}\text{compound}\right)\left(100\right)\%$
