Chapter 4, Problem 21E

Interpretation Introduction

Interpretation:

The limiting reactant, theoretical yield of ${\text{PbCl}}_{\text{2}}$ and the percent yield of the given reaction when $28.5\text{g}$

$\text{KCl}$ is added to a solution containing $\text{25}\text{.7}\text{g}{\text{Pb}}^{\text{2}+}$ is to be calculated.

Concept introduction: The number of moles is calculated by the formula,

$\text{Number}\text{of}\text{moles}=\frac{\text{Given}\text{mass}}{\text{Molar}\text{mass}}$

The percentage yield is calculated by the formula,

$\text{Percent}\text{yield}=\frac{\text{Actual}\text{yield}}{\text{Theoretical}\text{yield}}\times \text{100}$

To determine: The limiting reactant, theoretical yield of ${\text{PbCl}}_{\text{2}}$ and the percent yield of the given reaction when $28.5\text{g}$$\text{KCl}$ is added to a solution containing $\text{25}\text{.7}\text{g}{\text{Pb}}^{\text{2}+}$ .
