On a 10 day wilderness expedition you'll need to heat 4.0 kg of water to the boiling point each day. The air temperature will average 25 °C. You have available canisters of compressed propane (C,Hg) fuel, which you'll burn to heat the water. Each canister has 75. g of propane in it. What is the minimum number of fuel canisters you must bring? The standard heat of formation of propane at 25 °C is -103.85 kJ/mol. You'll probably find other helpful data in the ALEKS Data resource. canisters:

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
