Chapter 13, Problem 13.148QP

 (a)

Interpretation Introduction

Interpretation:

Van’t Hoff factor for fluorosilicic acid has to be calculated.

Concept introduction:

Osmotic pressure is the pressure that is needed to stop osmosis. Osmotic pressure of the solution is directly proportional to the concentration of the solution. We can calculate osmotic pressure by using this formula is given by,

$\text{π = iMRT}$

Where,

$\begin{array}{l}\text{π- Osmotic pressure}\\ \text{i- van't Hoff factor}\\ \text{M- Molarity of the solution(mol/L)}\\ \text{R- Universal gas constant}\\ \text{T- Temperature (Kelvin)}\end{array}$

Molar mass: Molar mass is defined as mass of the chemical compound or chemical element divided by its amount.

$\text{molar mass = }\frac{\text{mass of the substance in grams}}{\text{moles}}$
