" (Molar mass of urea "=60gmol^(-1)" ) "

A 4% solution of non-volatile solute is isotonic with 0.702% urea solution Calculate the molar mass of the non-volatile solute. (Mola.r mass of urea = 60 g mol^(-1) )

Calculate the osmotic pressure of 0.05% urea solution in water at 20^(@) C. Given R = 0.0821 atm mol^(-1)K^(-1) . Molar mass of urea = 60 g mol^(-1) .

22.22 gram of urea was dissolved in 300 grams of water. Calculate the number of moles of urea and molality of the urea solution. (Given : Molar mass of urea = 60 gram mol^(-1) )

At room temperature, a dilute solution of urea is prepared by dissolving 0.60 g of urea in 360 g of water. If the vapour pressure of pure water at this temperature is 35 mm Hg, lowering of vapour pressure will be: (molar mass of urea =60 g "mol"^(-1) )

At room temperature, a dilute solution of urea is prepared by dissolving 0.60 g of urea in 360 g of water. If the vapour pressure of pure water at this temperature is 35 mm Hg, lowering of vapour pressure will be: (molar mass of urea =60 g "mol"^(-1) )

Calculate number of atoms of hydrogen present in 5.6 g of urea (molar mass of urea = 60 g moI^-1 ).Also calculate the number of atoms of N,C and O.
