Calculate the amount of `CO_2` dissolved at 4 atm in `1dm^3` of water at 298K. The Henry's law constant for `CO_2` at 298K is 1.7 k bar.

When a gas is bubbled through water at 298K, a very dilute solution of the gas is obtained. Henry's law constant for the gas at 298K is 100 kbar. If the gas exerts a partial pressure of 1 bar. The number of millimoles of the gas dissolved in one litre of water is

If N_2 gas is bubbled through water at 293 K, how many millimoles of N_2 gas would dissolve in 1 litre of water? Assume that N_2 exerts a partial pressure of 0.987 bar. Given that Henry's law constant for N_2 at 293 K is 76.48 kbar.

Calculate the oxidation number of K in K2CO3

At what partial pressure, oxygen will have a solubility of 0.06 gL^-1 in water at 293 K? Henrys law constant (k_H) of O_2 in water at 303 K is 46.82 k bar. (Assume the density of the solution to be and same as that of water)

Calculate the amount of KCl which must be added to 1 kg of water so that its freezing point is depressed by 2 K.

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

If N_2 gas is bubbled through the water is 293K, how many millimoles of N_2 gas would dissolve in 1 litre of water. Assume that N_2 exerts a partial pressure of 0.987 bar. The K_H for N_2 at 293K is 76.48 K bar.
