Q74 / 200 · NEET 2022 (Phase 1) · Chemistry

In one molal solution that contains $0.5$ mole of a solute, there is

Correct answer
A
$500 g$ of solvent
B
$100 mL$ of solvent
C
$1000 g$ of solvent
D
$500 mL$ of solvent

Solution

Molality $= \frac{n_{solute}}{Mass of Solvent (kg)}$

Mass of solvent $= \frac{n_{solute}}{Molality}$

Mass of solvent $= \frac{0.5}{1} = 0.5 kg$ or $500 gm$ .

Hence, the correct answer is option: 'A'.
