Chapter 16, Problem 42E

Interpretation Introduction

Interpretation:

The mass of zinc iodide needed for preparation of $2.50\times {10}^2\text{mL}$ of $0.150\text{ M}$ aqueous solution of the salt is to be calculated.

Concept Introduction:

Molarity is defined as the number of moles present in one liter of solution. General expression is shown below.

$\text{Molarity}=\frac{\text{Moles}\text{of}\text{solute}}{\text{Volume}\text{of}\text{solution}}$

Measuring unit of molarity is $\text{mol}/\text{L}$ or $\text{molar}\left(\text{M}\right)$.
