Chapter 6, Problem 6.107SP

Interpretation Introduction

Interpretation:

The molarity of the $\text{Zn}{\left({\text{NO}}_{\text{3}}\right)}_{\text{2}}$ in the solution has to be calculated.

Concept introduction:

Number of moles:

One mole is the equal to number of atoms in $\text{12g}$ of carbon $\text{-12}$ which is equal to $\text{6}{\text{.023×10}}^{\text{23}}$ atoms. This is also known as Avogadro number.

Number of moles can be calculated as:

Number grams of solute = $\text{moles}\text{of}\text{solute}\text{×}\text{molar}\text{mass}\text{of}\text{the}\text{solute}$

Molarity:

The molarity of the solution can be determined as the number of moles of solute per one liter solution

Molarity =$\frac{\text{no}\text{of}\text{moles}\text{of}\text{solute}}{\text{no}\text{of}\text{litres}\text{of}\text{solution}}$
