JEE Previous Year Question

$Molality of 0.8 MH_{2} SO_{4} solution (density 1.06 g cm^{- 3}) is______\times 10^{- 3} m .$

Topic: JEE PYQ

Answer: 815. Full step-by-step solution below.

Correct answer: 815

(815) m = \frac{M \times 1000}{d _{sol} \times 1000 - M \times Molar mass solute} 815 \times 10^{- 3} m
