Chemistry Question on Solutions
According to Raoult?s law, the relative lowering of vapour pressure for a solution is equal to
A
mole fraction of solute
B
mole fraction of solvent
C
moles of solute
D
moles of solvent
Answer
mole fraction of solute
Explanation
Solution
Since relative lowering of vapour pressure is a colligative property, therefore it depends upon the number of solute particles or mole fraction of solute.
