moles = mass / (molecular weight x avogadro's constant)
avogadro constant = 6.02 x 10^23
molecular weight is something that you can find on the data booklet.
you can't leave the mass just like tt.
the m you wrote is moles not mass.
may i ask you wad you actually mean by 1Q2. delta heat energy...
Its a isochoric process.
you are right about no work done.
using Q = n Cv delta T,
what is left is finding how much moles of air is heat.
if not given, just treat it as a variable. more information required. the mass of gas will tell you how many moles there are.
1) Change the voltage source into a current source using source conversion.
i.e current source with current = 12V / 4ohm= 3 A. - lookin at the left voltage source.
you will get 3A current source with a resistor of 4 ohm connecting parallel to it.
do for the other side(right) too...

my 5 cents advice: look at the diagram in terms of rope distance.
the traveling path of C will be something like:
the ropes on the right side will lossen at the rate of twice of the velocity of collar B.
This makes C falls.
the rope on the left connecting C to A will pull up C at a rate of...
after considerin the 2 force members connected to the "ruler", i realize its no longer indeterminate.
I resolved the reaction at B using moments at the intersection of tension and the force by de member.
And solve the tension to be 292.1 N.
(Question solved)
Is this another statically indeterminate structure? (urgent)
