Chapter 5, Problem 5.130AP

Interpretation Introduction

Interpretation: The amount of $\text{NaOH}\left(\Delta H_{\text{soln}}=-44.3\text{kJ}/\text{mol}\right)$ required to raise the temperature back to $16.2°\text{C}$ for the given values is to be stated.

Concept introduction: The mass of $\text{NaOH}$ required $\left(m_{\text{NaOH}}\right)$ is calculated by the formula,

$m_{\text{NaOH}}=\frac{m_{{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}}\times M_{\text{NaOH}}}{M_{{\text{K}}_{\text{2}}{\text{SO}}_{\text{4}}}}$

To determine: The amount of $\text{NaOH}\left(\Delta H_{\text{soln}}=-44.3\text{kJ}/\text{mol}\right)$ required to raise the temperature back to $16.2°\text{C}$ for the given values.
