Chapter 13, Problem 92IL

Interpretation Introduction

Interpretation Empirical formula and molecular formula of the compound is to be determined.

Concept introduction:

Colligative properties: Properties of solutions which having influence on the concentration of the solute in it. Colligative properties are,

• Decrease in the vapor pressure
• Increase in the boiling point
• Decline in the freezing point
• Osmotic pressure

Osmotic pressure: The pressure created by the column of solution for the system at equilibrium is a measure of the osmotic pressure and is calculated by using the equation,

  $\pi =cRT$

  where,

  c is the molar concentration

The number of moles of any substance can be determined using the equation

  $\text{Number}\text{of}\text{mole}\text{=}\frac{\text{Given}\text{mass}\text{of}\text{the}\text{substance}}{\text{Molar}\text{mass}}$

Empirical formula: The simplest integer ratio of the element in a chemical formula. It can be obtained by reducing the ratio of elements to the simplest integer form of a molecular formula.
