Question

b) mole/ ml
0.1 gram mole of urea is dissolved in 100g of water. The molality of the solution is
a) 0.1 m
b) 0.01 m
c) 0.001 m
d) 1.0 m
16 of methanol is present in 100 ml of the solution If the density of the solution is 0.96 g/l​

Answer 1

Answer:

1.0m

Explanation:

Moles of urea =0.1 mole

Mass of Solvent (H

2

O)=100 g=0.1 kg

Molality =

mass(solvent in kg)

moles(solute)

=

0.1

0.1

=1 molal

Hence, option D is correct.
