Colligative property?

What is the boiling point of a solution composed of 17.0 g of urea, (NH2)2CO, in 0.850 kg of water?

kb (water) = 0.5121 oC/m kf (water) = -1.86 oC/m kb (chloroform) = 3.63 oC/m bp of chloroform = 61.70 oC

Molar mass of (NH2)2CO = 16*2 + 28 = 60

Thus boiling point = 100 + (60/17)*0.5121/0.85 =

102.126367 deg C
