Class 9th Chemistry Chapter 6 Exercise Numericals With Solutions

Chemistry can feel overwhelming, especially when solving complex numerical problems. Chapter 6 of Class 9th Chemistry, focusing on solutions and solubility, holds significant importance in the curriculum.

To simplify your learning, these exercise-solved numericals provide clear step-by-step explanations, saving time and ensuring accuracy. Designed to strengthen your conceptual understanding, these notes are a vital tool for acing exams with confidence.

Exercise Solved Numericals

Numericals form a critical part of Chapter 6. Here’s an example breakdown from the notes:

1. Concentration in % Mass/Volume (m/v):

A solution contains 5g of solute dissolved in 95g of solvent. The concentration is calculated using the formula:

Concentration (% m/v) = (Mass of solute / Mass of solution) × 100

Example calculation:

Concentration = (5 / (95 + 5)) × 100 = 5% (m/v)

2. Molarity Calculations:

For example, dissolving 20g of NaCl (Molar Mass = 58.5 g/mol) in 0.4 liters of solution yields a molarity of:

M = Mass of solute / (Molar Mass × Volume of solution in dm³)

Result:

M = 20 / (58.5 × 0.4) = 0.85 M

These numericals simplify complex calculations and are structured to build confidence for exams.
