<p style="margin-top:0;margin-bottom:0">Just to clarify, in the
equation for determining the molar mass of the unknown gas.
(M=mRT/PV), the known mass value for the equation is supposed
to be the mass of the entire system? I've just been getting
some weird numbers for the molar mass of the unknown gas.
Thank you</p>

<p>Mass should be ONLY for the gas -- (mass of gas, flask,
aluminimum foil, rubber band) - ( mass of empty flask, aluminum
foil, rubber band)</p>
