  1. The long way.
    PV = nRT
    Solve for n, then n = g/molar mass. Solve for molar mass.
    Redo PV = nRT, solve for V under the new conditions.

    Easier way.
    42.9 is 0.1 of the initial so at the same T and P, V = 0.1 x 25.6 or 2.56 L.
    Then correct for the temperature difference.
    2.56 x 326/322 = ??
