1. The solubility of a gas is 0.34 g/L at STP. What

is its solubility at a pressure of 0.80 atm and

the same temperature?

2. At 25°C and 1.0 atm, 0.25 g of a gas dissolves

in 1.00 L of water. What mass of the gas dissolves

in 1.00 L of water at 25°C and 3.0 atm?

3. 1.56 g of a gas dissolves in 2.00 L of water at a

pressure of 1.75 atm. At what pressure will

2.00 g of the gas dissolve in 2.00 L of water if

the temperature remains constant?
