Conservation of mass

  1. Jul 13, 2007 #1
    Any help is greatly appreciated,

    A 3-liter vessel contains 2kg of water, 0.05kmol of steam, and 15cm3 of ice (density = 990kg/m3). If the vessel is heated until its entire contents have vaporized, what is the density of the vapor?

    now i know i've to use M(in) - M(out) = M(vessel). If anyone can guide me on how to start it, i'd appreciate it.

    Thank you

    Is it a closed vessel? If so, this is not much more than a unit conversion problem.
