Solutions Question 186

Question: The molality of 90% H2SO4 solution is [density=1.8 gm/ml] [MP PMT 2004]

Options:

A) 1.8

B) 48.4

C) 9.18

D) 94.6

Show Answer

Answer:

Correct Answer: C

Solution:

The density of solution =1.8,gm/ml Weight of one litre of solution =1800,gm
Weight of H2SO4 in the solution =1800×90100 =162gm
Weight of solvent =18001620=180,gm
Molality =162098×100180=9.18
