CH3OH(g) CO(g) + 2 H2(g) H = +90.7 kJ .

Question

Calculate the amount of heat transferred when 35.0 g of CH3OH(g) are decomposed by this reaction at constant pressure

Answer 1

You forgot to include an --> in your reaction.

Convert 35.0 g of methanol to moles

The units of your reaction should have been kJ per mole of CH3OH.

All you have to do is multiply kJ/mole by moles
