CH3OH CO + 2H2 H = +90.7kJ
9. For the forward reaction, is heat being absorbed or released?
10. How much heat would be transferred if 45.0 g of CH3OH is decomposed?
11. What quantity of CH3OH decomposition would lead to an enthalpy change of 18.5 kJ

delta H is + which means heat is being absorbed.
1 mole CH3OH (32 g) absorbs 90.7 kJ heat. So 45 g CH3OH will absorb 90.7 x (45.0/32.0) = ??
Just use the above and plug in the numbers.
90.7 kJ x (grams CH3OH/32.0) = 18.5 kJ. Solve for grams CH3OH
