A) moles of solute
B) mole fraction of solvent
C) moles of solvent
D) mole fraction of solute
Correct Answer: D
Solution :
According to Raoulfs law, the relative lowering of vapour pressure of solution is equal to mole fraction of solute. \[\frac{p-{{p}_{s}}}{{{p}_{s}}}={{X}_{B}}\] where, \[p=\]Vapour pressure of pure solvent \[{{P}_{s}}=\]Vapour pressure of solution \[{{X}_{B}}=\]Mole fraction of soluteYou need to login to perform this action.
