Chapter F, Problem E.1BST

Interpretation Introduction

Interpretation:

Number of hydrogen atoms present in $\text{3}\text{.14}\text{mol}$ of ${\text{H}}_{\text{2}}\text{O}$  has to be calculated.

Concept Introduction:

Mole of a substance is defined as the substance that contains the same number of substance as there are the number of atoms present in $\text{12}\text{g}$ of carbon-12 isotope.  One mole of any substance contains Avogadro’s number of substance.

    $\begin{array}{c}\text{Number}\text{of}\text{objects}=\text{amount}\text{in}\text{moles}\times \text{Avogadro's}\text{constant}\\ N=n{N}_A\end{array}$

Where,

    $n$ is the amount in moles.
