#heat=(1.2/2)*DeltaH_"reaction"#

I am also making some assumptions
1) the reaction is exothermic
2) you know the enthalpy change for the reaction #DeltaH#

The reaction reads 2 moles of A reacts with 3 moles of B to make C. If you know the enthalpy #DeltaH# value for reaction, you would know the joules of heat released for each mole of C produced.

2 moles of A would yield this much heat making 1 mole of C (reacting with excess B).

#heat=("moles of A"/2)*DeltaH_"reaction"#

alternatively

#heat=("moles of B"/3)*DeltaH_"reaction"#

or for moles of C yielded

#heat=("moles of C")*DeltaH_"reaction"#
