    Hey,

    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

    The exercise seems to be just converting kmol and cm^3 into mass units so that you can work out the total mass in the system (conservation of mass). From that and the fact that the vapour will expand to fill the container (i.e. volume = 3 litres) you can work out its density.
