Methane, CH4 is the main component of natural gas which is used for cooking in many homes. The molar heat of combustion of methane is -890kj/mol. A cook wants to boil some water on a gas stove. If the stove burns 5.00g of methane to heat 2575 ml of water, what is the temperature rise of the water?

Answer 1

mols CH4 = grams/molar mass.
Then q produced = 890 kJ/mol x ? mols from above = ?
Then q produced = mass H2O x specific heat H2O x (Tfinal-Tinitial)
