Question

The molal lowering of vapour pressure of a liquid is 1.008 mm of Hg at in a very dilute solution containing non volatile solute. The vapour pressure of liquid at is of Hg. The value of is (molecular weight of liquid = 18)​

Answer 1

Explanation:

Molal lowering of vapour presure of liquid is 1.008 mm Hg at 25°C

in very dilute solution. The vapour pressure of liquid at

is 25°C

mm Hg. The value of

X

is (molecular mass of liquid is

18g mol-1
