A sample of the liqid `H_(2)O` at 18.0 g is injected into an evacuated 7.6 L flask maintained at `27.0^(@)C`. If vapour pressure of `H_(2)O` at `27.0^(@)C` is 24.63 mm Hg, what weight percentage of the water will be vaporised when the system comes to equilibrium? Assume water vapours behaves as an ideal gas. The volume occupied by the liquid water is negligible compared to the volume of the container:
A
0.01
B
0.1
C
0.18
D
0.2

The vapour pressure of water at 20^@C is 17.54mm Hg. then the vapour pressure of the water in the apparatus shown after the piston is lowered, decreasing the volume of the gas above the liquid to one half of its initial volume (temp. constant) is
The volume occupied by O_2 gas at STP which is obtained by the decomposition of 17g of H_2O_2 is
A sample of an ideal gas has a volume of 0.5 litres at 27^@C and 750mm pressure. The number of moles of gas are
The vapour pressure of water at 23^(@)C is 19.8 mm. 0.1 mole of glucose is dissolved in 178.2 g of water. What is the vapour pressure (in mm) of the resultant solution?
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?
The vapour pressure of water at room temperature is 23.8 mm Hg. The vapour pressure of an aqueous solution of sucrose with mole fraction 0.1 is equal to :
Vapour pressure of pure water at 298 k is 23.8 mm Hg. Calculate the lowering of vapour pressure caused by adding 5g of sucrose in 50 g of water.
