12.0 g urea is dissolved in 1 litre of water and 68.4 g sucrose is dis – InterviewSolution

1.	12.0 g urea is dissolved in 1 litre of water and 68.4 g sucrose is dissolved in 1litre of water. The relative lowering of vapour pressure of urea solution is
Answer» greater than SUCROSE solution less than sucrose solution double that of sucorse solution equal to that of sucrose solution. Solution :`"12 G urea "(NH_(2)CONH_(2))=(12)/(60)" MOL"=(1)/(5)" mol"="0.2 mol"` `"68.4 g sucrose "=(68.4)/(342)" mol"=(1)/(5)"mol"="0.2 mol"` As molar concentrations are equal, relative lowering of VAPOUR pressures will also be equal.
