What partial pressure of oxygen above the water (in atmospheres at 0 C ) is needed to obtain this concentration? The solubility of O2 in water at 0 C and 1 atm partial pressure is . 2.21 x 10^-3 mol/L

Concentration needed is 4mg/L
Stuck and need help, anything is appreciated!

p = KcC
Kc = p/C = 1/2.21E-3 = ?
Then revisit p = KcC
You want p, you know Kc and convert 4 mg/L to C in mols/L and solve for p
