  1. I think you meant 4.33 g/liter and  NOT 4.33 g/mL

    Calculate the moles per 1 liter-

    n = PV/RT = 0.9934 atm x 1.000 L / (0.08206 x 728 K)

    n = 0.01663 moles per liter

    0.01663 moles = 4.33 g/molar mass

    molar mass = 260.4

    260.4 / 32.066 = 8.1

    S8 = molecular formula of sulfur vapor
