Answer: To calculate the enthalpy of combustion of acetylene, C2H2 , all you have to do is ... More specifically, you need to subtract from the sum of enthalpies of ... chemical reaction has 2 moles of C2H2 reacting to produce 2 moles of ... since the heat of combustion is expressed as energy per mole
To answer this question, all you to do is to divide the mass by the molar mass and that should get you your moles.

<em>= 3.5 mol NH₄</em>
