At 25 *C and 0% salinity the amount of oxygen in the ocean is 5.77 mL/L. What is the molarity of oxygen in the ocean at these conditions?

Assuming 1 atm pressure, use the ideal gas law to calculate moles of O2 in 5.77 mL:
PV = n RT
1 atm (0.00577 L) = n (0.08206 Latm/molK) (298 K)
n = 2.36X10^-4 mol O2
So, the molarity of O2 is 2.36X10^-4 mol/L
