The density of a solution prepared by dissolving 120 g of urea ( mol. Mass = 60 u) in 1000 g of water is 1.15 g/mL. The molarity of this solution is

A

0.50 M

B

1.78 M

C

1.02 M

D

2.05 M

Text Solution

Verified by Experts

Total weight of solution `=1000+120=1120g`
Molarity `=120/60xx1000/(1120//1.15)=2.05M`
