Henry's law constant for CO_2 in water is 1.67xx10^8 Pa at 298 K. Calculate the quantity of CO_2 in 500mL of soda water when packed under 2.5 atm CO_2 pressue at 298K.

If N_2 gas is bubbled through water at 293K how many milliomoles of N_2 would be dissoved in 1 litre of water? Assume that N_2 exert sa partial pressure of 0.987 bar. Given that Henrey's law constant for N_2 at 293K is 76.48K bar.

The air is a mixture of a number of gases. The major components are oxygen and nitrogen with approximate proportion of 20% is to 79% by volume at 298 K. The water is in equilibrium with air at a pressure of 10 atm. At 298 K if the Henry's law constants for oxygen and nitrogen are 3.30xx10^7 mm and 6.51xx10^7 mm respectively, calculate the composition of these gases in water.

A solution containing 30g of non-volatile solute exactly in 90g of water has a vapour pressure of 2.8 kPa at 298 K. Further, 18 g of water is then added to the solution and the new vapour pressure becomes 2.9 kPa at 298 K. Calculate: molar mass of the solute
