Interpretation Introduction

Interpretation:

The sample containing the greatest mass of calcium out of the samples of calcium citrate $\left({\text{Ca}}_3{\left({\text{C}}_6{\text{H}}_5{\text{O}}_7\right)}_2\right)$ and calcium phosphate $\left({\text{Ca}}_3{\left({\text{PO}}_4\right)}_2\right)$ is to be determined.

Concept Introduction:

The calculation of the number of moles is expressed as follows:
