SUMMARY
The maximum mass of O2 that can dissolve in 1L of water at 25°C with a partial pressure of 40 mmHg is calculated using Henry's Law. The relevant equation is partial pressure = kH * concentration, where kH for O2 is 769.2 L*atm/mol. By converting 40 mmHg to atm (40 mmHg = 0.05263 atm), the concentration of O2 can be determined. This results in a specific concentration value that can be further converted to mass using the molar mass of O2.
