Chemistry

A 200-L home heater tank contains butane gas (C4H10) at 26.0 Â°C.When some of the butane
is removed and burned in excess air, the pressure in the tank dropsfrom 2.34 atm to 1.10 atm.
The energy generated in the combustion is then used to raise thetemperature of 132.5 L of
water from 19.0Â°C to 71.3 Â°C.
Useful Information:
Î”HÂ°f (CO2 (g)) = â€“393.5 kJ/mol Î”HÂ°f (H2O (l)) = â€“285.8 kJ/molDensity of water = 1 g/mL
â†’Calculate the enthalpy of formation (Î”HÂ°f) of butane gas.
