Chapter 13, Problem 21PE

Interpretation Introduction

Interpretation:

Mass percent of water in $\text{cobalt}\left(\text{II}\right)\text{ hexahydrate}$ $\left({\text{CoCl}}_2\cdot 6{\text{H}}_{\text{2}}\text{O}\right)$ has to be calculated.

Concept Introduction:

Mass percent is one of the commonly used concentration terms to determine concentration of any species. The expression for mass percent of any species present in sample is as follows:

  $\text{Mass percent}=\left(\frac{\text{Mass of species}}{\text{Mass of sample}}\right)\left(100\text{ \%}\right)$
