Chapter 4, Problem 41E

Interpretation Introduction

Interpretation:

The limiting reactant, theoretical yield of ${\text{PbCl}}_{\text{2}}$ and the percent yield of the given reaction when $25.0\text{mL}$ sample of a $1.20\text{M}$ potassium chloride solution is mixed with $15.0\text{mL}$ of a $0.900\text{M}\text{lead}\left(\text{ΙΙ}\right)\text{nitrate}$ solution 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 $25.0\text{mL}$ sample of a $1.20\text{M}$ potassium chloride solution is mixed with $15.0\text{mL}$ of a $0.900\text{M}\text{lead}\left(\text{ΙΙ}\right)\text{nitrate}$ solution.
