How much heat is released in the formation of 10 liters of NH3(g) at 25 C and 1 atm, given :

2N2+3H2 ----> 2 NH3
HEAT OF FUSION IS - 92.6 KJ

show steps please

I wonder if heat of fusion is supposed to be heat of reaction? If so, then use PV = nRT to convert 10 L NH3 at the conditions listed to n = number of moles of NH3. Convert moles NH3 to grams NH3. g = moles x molar mass. Then

92.6 kJ x ??grams NH3/34 = ?? kJ.
