Chapter 13, Problem 72QP

Interpretation Introduction

Interpretation:

The osmotic pressure for ${\text{MgSO}}_4$ solution at given temperature is to be calculated.

Concept introduction:

The equation of osmotic pressure for a solution is as follows:

$\pi =iMRT$

Here, $\pi$ denotes osmotic pressure, $i$ denotes the van’t Hoff factor, $M$ denotes the molarity of solute, $R$ denotes the universal gas constant $\left(0.0821\text{ L}\cdot \text{atm/mol}\cdot \text{K}\right)$, and $T$ denotes the temperature.

The equation for the conversion of degree Celsius $\left[T\left({\text{H}}^{\circ }\text{C}\right)\right]$ into Kelvin $\left(T\right)$ is as follows:

$T=T\left({}^{\circ }\text{C}\right)+273$
