The boiling point of 0.2 mol kg^(-1) solution of X in water is greater than equimolal soltuion of Y is water. Which one of the following stamtements is true in this case

Answer»

MOLECULAR mass of X is greater than the molecular of Y
Molecular mass of X is LESS than the moelcular mass of Y
Y is undergoing DISSOCIATION in water while X UNDERGOES no change
X is undergoing dissociation in water

Solution :When SOLUTE undergoes dissociation than vant Hoff factor `i gt Delta T_(b)= i K_(b) m`
