Question

The heater used in a 4.23 m x 3.59 m x 2.88 m dorm room uses the combustion of natural gas (primarily methane gas) to
produce the heat required to increase the temperature of the air in the dorm room. Assuming that all of the energy produced in
the reaction goes towards heating only the air in the dorm room, calculate the mass of methane required to increase the
temperature of the air by 6.39 °C. Assume that the specific heat of air is 30.0 J/K-mol and that 1.00 mol of air occupies 22.4 L at
all temperatures. Enthalpy of formation values can be found in this table. Assume gaseous water is produced in the combustion
of methane.
mass of methane:
