If 0.0225 g of a gas dissolves in 2.73 l of water at 758 torr, at what pressure would you be able to dissolve 0.134 g in the same amount of water?

Answer : 4514.311 torr

Explanation : Using henry's law in simplified version;



where is the concentration of gas in first case which is 0.0225 g
 and 
is the concentration of gas in second case which is 0.134 g

the concentration of water is ignored as it remains the same in both the cases.

And, is 758 torr and needs to be found.

on substituting the values we get, = (0.134 X 758) / 0.0225 = 4514.311 torr
