Chapter 13, Problem 118E

Interpretation Introduction

Interpretation:

The volume of $1.50M$ sodium sulfate solution which is required to completely precipitate all of the barium from 0.250 M barium nitrate solution is to be calculated.

Concept introduction:

The number of moles of the solute per liter of solution is called molarity.

$\text{M=}\frac{\text{Moles solute}}{\text{Liters solution}}$ …… (1)

The volume of solution should be in liters.

Liters to moles conversion: $\frac{\text{moles of solute}}{\text{ L solution}}$

Moles to liters conversion: $\frac{\text{L solution}}{\text{moles of solute}}$

Mole to mole conversion: $\frac{\text{number of moles of A}}{\text{number of moles of B}}$

To convert $\text{mL}$ to liters $\left(\text{L}\right)$, conversion factor will be $\left(\frac{{10}^{-3}\text{ L}}{\text{1 mL}}\right)$.

To convert $\text{L}$ to milliliters $\left(\text{mL}\right)$, conversion factor will be $\left(\frac{{10}^3\text{ mL}}{\text{1 L}}\right)$.
