We would generate 2xx-128*kJ.......

Explanation:

We has..........

"Moles of dihydrogen" = (8.08*g)/(2.02*g*mol^-1)=4.0*mol

CO(g) + 2H_2(g) rarr CH_3OH(l) ;DeltaH_"rxn"=-128*kJ.

Enthalpy terms are written per mole of reaction as written. We reduce 4 moles of carbon monoxide, and should therefore generate 2xx-128*kJ=-256*kJ.
