Chapter 2, Problem 2.61E

Interpretation Introduction

Interpretation:

The mass percentage of calcium in ${\text{CaCO}}_3$ and ${\text{CaMgC}}_{\text{2}}{\text{O}}_{\text{6}}$ is to be determined.

Concept introduction:

Molar mass is the sum of the atomic masses of all the atoms present in the chemical formula of any compound.

The formula to calculate mass percent composition for each element is,

$\text{Mass}\%=\frac{M_1}{M_w}\times 100$
