Chapter 4, Problem 4.5MP

Interpretation Introduction

Interpretation:

The mass of $\text{KBr}$ used to make $250.0\text{ml}$ of a $1.50\text{M}$

$\text{KBr}$ solution is to be calculated.

Concept introduction: Molarity is defined as the number of moles of solute that dissolves in per liter of a solution. Molarity is calculated by the formula,

$\text{Molarity(M)}=\frac{\text{Amount}\text{of}\text{solute}\text{(in}\text{mol)}}{\text{Volume}\text{of}\text{solution}\text{(in}\text{L)}}$

To determine: The mass of $\text{KBr}$ used to make $250.0\text{ml}$ of a $1.50\text{M}$

$\text{KBr}$ solution.
