Working Eqn ----> PV=nRT
where--->
For n?
n=mass%2Fhighlight%28MW%29,
where, MW=%28Number+ofAtoms%29%28AtomicWeight%29
Look thru the Table, you see Nitrogen has "14" Atomic Weight, so having with "2" atoms, it's MW=2%2A14=28
Subst.---> n=30cross%28g%29%2F%2828cross%28g%29%2Fmol%29
n=1.07143moles
.
Going Back Working Eqn,
%282.25%29%280.550%29=%281.07143%29%280.0821%29%28T%29
1.2375=0.0879644%28T%29 ---> cross%281.2375%2914.07%2Fcross%280.0879644%29=cross%280.0879644%29T%2Fcross%280.0897644%29
highlight%28T=14.07%28K%29%29, Answer
.
