If a sample of Helium gas is collected over water, what is the pressure of the dry gas alone if the total pressure is 760.0 mmHg and the partial pressure of water is 20.0 mmHg?

  • Chemistry -

    Dalton's Law of Partial Pressure says that the total pressure is the sum of the partial pressure of each gas. Ptotal = PHe + PH2O
