Question
The vapour pressure of benzene at 30oC is 121.8 mm. By adding 15g of non-volatile solute in 250 g of benzene, its molecular weight of solute is :
Options
A.156.6g
B.267.4 g
C.356.3 g
D.467.4 g
Solution
According to Raoult′s law,
∴ m =
= 356.265 g
∴ m =
= 356.265 gCreate a free account to view solution
