Calculate the relative lowering in vapour pressure if 100 g of a nonvolatile solute.(mol.wt.100 ) are dissolved in 432 g watere.

Calculate the relative lowering in V.P. if 10 g of a solute (molar mass 100) are dissolved in 180g water.

The vapour pressure of a pure liquid at 25^(@)C is 100 mm Hg. Calculate the relative lowering of vapour pressure if the mole fraction of solvent in solution is 0.8.

The vapour pressure of a pure liquid at 25^(@)C is 100 mm Hg. Calculate the relative lowering of vapour pressure if the mole fraction of solvent in solution is 0.8.

What do you mean by relative lowering of vapour pressure? Calculate the relative lowering of Vapour pressure of a solution formed by dissolving 50 g of urea (NH_2 CONH_2) in 850g of water.(Given vapour pressure of pure water at 298K= 23.8mm of Hg.)

The relative lowering of vapour pressure produced by a solution of 18 g of urea in 100 g of water is approximately

18g glucose is dissolved in 90g water. The relative lowering of vapour pressure is equal to

A solution is prepared by dissolving 10 g of nonvolatile solute in 180 g of H_2O . If the relative lowering of vapour pressure is 0.005, find the mol. wt. of the solute.
