Question

mole fraction of water in 98% h2so4 (w/W) solution is​

Answer 1

Answer:

Hi frnd.....

Density = 2.08 g/cc (assuming)

Weight of 1 litre of solution = 2.08 *1000 = 2080g

gram molecular weight of H2SO4 = 98g

Moles of H2SO4 = (2080-1000)/98 = 11.02 moles( 1 litre = 1000g and density of water=1)

moles of water = 1000/18 = 55.56

Mole fraction = 11.02/11.02+55.56 = 0.166.

Hope this answer helps you
