What is the density of propene gas measured at 2.5 atm and 47C? I know that I use the combine gas law, but I don't know how to find "n" in this particular problem. Please help ASAP!
The general gas law equation, PV = nRT, can be modified for density, so that one can calculate density without actually going through n.
P*molar mass = density*R*T.
Remember T must be in K.
Solve for density.
