How much heat, in kilojoules, is evolved in the complete combustion of (a) 1.325 g C 4

Question:

How much heat, in kilojoules, is evolved in the complete combustion of 

(a) 1.325 g C4H10(g) at 25 °C and 1 atm; 

(b) 28.4 L C4H10(g) at STP;

(c) 12.6 L C4H10(g) at 23.6 °C and 738 mmHg?

Assume that the enthalpy of reaction does not change significantly with temperature or pressure. The complete combustion of butane, C4H10(g), is represented by the equation

C4H10(g) + O(g) 13 2 4 CO2(g) + 5H0 (1) A,H -2877 kJ mol
