A solution of glucose has been prepared at 298K dissolving 7.2 g of glucose in 100 g of water. k_f water is 1.86Km^-1 and vapour pressure of water at 298K is 0.024 atm. The vapour pressure of the solution at 298K will be
The degree of dissociation of Ca(NO_3)_2 in dilute aqueous solution containing 7.0 g of the salt per 100 g of water at 100^@C is 70 percent. If the vapour pressure of water at 100^@C is 760 mm, calculate the vapour pressure of the solution.
An aqueous solution of glucose is made by dissolving 10 g of glucose (C_6H_12O_6) in 90 g of water at 303 K. if the vapour pressure of pure water at 303 K be 32.8 mm Hg, what would be the vapour pressure of the solution?
100 g of liquid A (molar mass 140 g mol^(-1) was dissolved in 1000 g of liquid B (molar mass 180 g mol^(-1)) . The vapour pressure of pure liquid B was found to be 500 torr. Calculate the vapour pressure of pure liquid A and its vapour pressure in the solution if the total vapour pressure of the solution is 475 Torr.
1.0 gram of a non-volatile solute was dissolved in 100 gram of acetone (molecular mass = 58) at 298 K. The vapour pressure of solution was found to be 192.5 mm of Hg. Calculate the molecular mass of solute. The vapour pressure of pure acetone at 298 K is 195 mm of Hg.
Vapour pressure of pure water at 298 k is 23.8 mm Hg. 50 g of urea (NH_2CONH_2) is dissolved in 850 g of water. Calculate the vapour pressure of water for this solution and it's relative lowering.
What mass of a non-volatile solute, urea (NH_2CONH_2) need to be dissolved in 100 g of water in order to decrease the vapour pressure of water by 25%? What is the molality of the solution?
Why the vapour pressure of a solution of glucose in water is lower than of pure water
Vapour pressure of water at 20^C is 17.5 mm of Hg and lowering of vapour pressure of a sugar soluton is 0.061 mm of Hg. Calculate vapour pressure of the solution.
