300 g of water at 25^(@)C is added to 100 g of ice at 0^(@)C . The final temperature of the mixture is
The weight of urea to be dissolved in 100 g. of water to decrease the vapour pressure of water by 5% is
6 g of urea is dissolved in 90g of boiling water. The vapour pressure of the solution is
Vapour pressure in mm Hg of 0.1 mole of urea in 180 g of water at 25^(@)C is (The vapour pressure of water at 25^(@) C is 24 mm Hg)
139.18 g of glucose is added to 178.2 g of water the vapour pressure of water for this aqueous solution at 100^@ C is
When 25 g of a non-volatile solute is dissolved in 100g of water, the vapour pressure is lowered by 2.25 xx 10^(-1)mm . If the vapour pressure of water at 20^(@)C is mm, what is the molecular weight of the solute?
At 298 K, the vapour pressure of a solution of 7.5 g of non-volatile solute in 90 g of water is 2.8 kPa. If 18 g of water is added to this solution vapour pressure becomes solution the vapour pressure becomes 2.81 kPa at same temperature, the molar mass of solute in g mol^(-1) is
18 g of glucose is dissolved in 90 g of water. The relative lowering of vapour pressure of the solution is equal to
Vapour pressure of water of 293 K when 25 g of glucose is dissolved in 450 g of water.
