    There may be an easier way to do this (a graph but you didn't say you had one). You can use the Clausius-Clapeyron equation and solve for T2.
    ln (p2/p1) = (dHvap/R)(1/T1 - 1/T2)
    p1 = 760; T1 = 100
    p2 = 520; T2 = ?
    dHvap is heat vaporization in J. You'll need to look that up. T2 will be the boiling point of the water at 520 mm Hg pressure.
