Answer:
The energy released will be -94.56 kJ or -94.6 kJ.
Explanation:
The molar mass of methane is 16g/mol
The given reaction is:

the enthalpy of reaction is given as ΔH = -890.0 kJ
This means that when one mole of methane undergoes combustion it gives this much of energy.
Now as given that the amount of methane combusted = 1.70g
The energy released will be:

the system is in constant temperature
so it follows Boyle's law
i.e.P1V1=P2P2
where P1=initial pressure=788 tour
P2=final pressure= ?
V1=initial volume=235 ml
V2=final volume=0.115 ml
