Question:

The amount of ammonium sulphate required to prepare 2 litres of 2 molar solution is:

Options:

264 g

132 g

198 g

212 g

Correct Answer:

264 g

Explanation:

The correct answer is option 1. 264 g.

Molar mass of ammonium sulphate \(= 132 g/mol\)

Volume = \(2 L\)

Molarity \(= 1\)

\(Weight = \text{Molarity × Molar mass of ammonium sulphate × volume}\)

\(Weight = 1 × 132 × 2 = 264 g\)
