If .654 g of oxygen dissolves in 1.5 L of water at 1.65 atm, at what pressure would you be able to dissolve 1.35 g in the same amount of water?

To prevent the presence of air, noble gases are placed over highly reactive chemicals to act as inert "blanketing" gases. a chemical engineer places a mixture of noble gases consisting of 4.37 g of he, 13.36 g of ne, and 36.65 g of kr in a piston-cylinder assembly at stp. calculate the partial pressure in torr of kr.
