Interpretation Introduction

Interpretation:

The number of moles of cobalt $\text{(Co)}$ atoms present in $\text{6}\text{.00}{\text{×10}}^{\text{9}}\text{Co}\text{atoms}$ of $\text{(S)}$ has to be calculated.

Concept Introduction:

Moles:

Mole of the compound present in the solution is calculated by Avogadro number the compound multiplied with number of moles.

$\text{No}\text{. of moles = }\frac{\text{1}\text{mole}}{\text{6}\text{.022}\text{×}{\text{10}}^{\text{23}}\text{atom}}\text{×}\text{number}\text{of}\text{atoms}$
