Problem

Consider the following reaction:

CH(g) + 2 O2 (g) → CO2 (g) + 2H2O (l)             ΔH = -891 kJ

Calculate the enthalpy change for each of the following cases:

b. 1.00 x 103 L methane gas at 740. torr and 25°C are burned in excess oxygen. The density of CH4(g) at these conditions is 0.639 g/L.
