3g urea is dissolved in 45g of water. The relative lowering of vapour pressure is :
30 g of urea (M=60g mol^(-1) ) is dissolved in 846g of water. Calculate the vapour pressure of water for this solution if vapour pressure of pure water at 298 K is 23.8 mm Hg. (b) Write two differences between ideal solutions and non-ideal solutions,
6g of urea is dissolved in 90g of water. The relative lowering of vapour pressure is equal to
10 g of glucose (molar mass 180) and 20 g of sucrose (molar mass 342) are dissolved in 100 g of water. What will be the vapour pressure of the resultant solution if the vapour pressure of water is 30 mm Hg ?
How many grams of sucrose must be added to 360g of water to lower the vapour pressure by 1.19mm Hg at a temperatue at which vapour pressure of pure water is 25 mmHg ?
