f the solubility of a gas in water is 5.0g/L when the pressure of the gas above the water is 2.0 atm, what is the pressure of the gas above the water when the solubility of the gas is 1.0 g/L
Here's how to solve this one.
The formula for solubility is
P1 / P2 = solubility1 / solubility2
P1=2*1/5= .4 atm
So the correct answer is 0.4 atm.
