A) 0.8
B) 0.5
C) 0.3
D) 0.2
Correct Answer: D
Solution :
According to Raoult's law the relative lowering in vapour pressure of an ideal solution containing the non-volatile solute is equal to the mole fraction of the solute. \[\because \]Relative lowering of vapour pressure \[=0.2\] \[\therefore \]Mole-fraction of the solute\[=0.2\]You need to login to perform this action.
