Chapter 4.2, Problem 4.8PP

Interpretation Introduction

Interpretation:

The formula mass and molar mass of cobalt chloride hexahydrate (${\text{CoCl}}_{\text{2}}·{\text{6H}}_{\text{2}}\text{O}$) has to be calculated.

Concept Introduction:

Formula mass:

Formula mass of a compound is the sum of the atomic masses of all atoms in the compound.  It is expressed in $\text{amu}$.

Molar mass:

Molar mass is the mass (in grams) of one mole of a substance.  It is expressed in $\text{g/mol}$.

The molar mass of compound is numerically equal to the formula mass in $\text{amu}\text{.}$
