    2 Second Chemistry Question

    Trying to theoretically boil 1 L of water in a closed container at 90 degrees Celsius and using the correlating boiling pressure for water at this temperature. In order to find the size of the container I tried using the Ideal Gas Law with the following variables:

    V = solving for this.
    P = .697 atm
    n = 55.6 moles/liter
    R = .0821 (L*atm)/(mol*K)
    T = 363.15 K

    The result shows a volume of 2378.3 L needed to carry out this experiment. I believe I have made a mistake. Surely water could be boiled in a smaller vessel, right?

    Except that saturated steam at that pressure is not an ideal gas and has a compressibility factor of about 0.988, your number is correct.
