Explanation

This is a basic mass percentage calculation where the solute (benzene) is dissolved in the solvent (carbon tetrachloride). The mass percentage is calculated by dividing the mass of each component by the total mass of the solution and multiplying by 100.

Solution Steps

  1. Step 1: Calculate total mass of solution = Mass of benzene + Mass of CCl₄ = 22 g + 122 g = 144 g

  2. Step 2: Calculate mass percentage of benzene = (Mass of benzene / Total mass) × 100 = (22 g / 144 g) × 100 = 15.28%

  3. Step 3: Calculate mass percentage of carbon tetrachloride = (Mass of CCl₄ / Total mass) × 100 = (122 g / 144 g) × 100 = 84.72%
