C15H30 is a hydrocarbon that reacts with oxygen gas to give carbon dioxide and water.
Calculate the mass of water (grams) formed when 724.05 grams of the hydrocarbon reacts with the oxygen gas.
This is a stoichiometry problem. Here is a worked example. Just follow the steps. You need not convert grams to moles since you are given moles initially.
C15H30 +02 -> CO2 + H2O
Im having trouble balancing it.
2C15H30 + 45O2 ==> 30CO2 + 30H2O
