TE 303 - HW #1, P1 - Mass, Force, Density and Acceleration - 10 pts
A closed system consists of 0.5 lbmole of liquid water and occupies a volume of 0.145 ft3. Determine the weight of the system, in lbf, and the average density, in lbm/ft3, at a location where the acceleration of gravity is g = 30.5 ft/s2.

I have been asked this question a lot -- remember that lbmol is number of moles of the substance, which corresponds to the "n" in the PV=nRT equation. (No, you don't have to use the ideal gas law for this problem, I only used that equation since it's familiar to everyone.)
