NEET Chemistry Types of Solutions MCQ Question
What is the molality of a solution if 2 moles of glucose are dissolved in 500 grams of water?
4 mol kg⁻¹
0.5 mol kg⁻¹
2 mol kg⁻¹
1 mol kg⁻¹
Correct Answer
Detailed Explanation
Molality (m) is calculated as the number of moles of solute per kilogram of solvent. Here, 2 moles of glucose are dissolved in 0.5 kg of water, so the molality is 2 / 0.5 = 4 mol kg⁻¹.
