Question

In the chemical equation CH4 + O2 -> CO2 + 2H2O for every one mole of carbon dioxide you produced, how many moles of water would you have?

Answer 1

Answer: 2 moles

Step-by-step explanation:

In the balanced equation, it can be seen that everything reacts in a 1:1 mol ratio except water (H2O) as determined by the coefficient. It is simple stoichiometry, 1 mol CO2 * 2 mol H2O/1 mol CO2 = 2 mol CO2. After doing the math, the CO2 cancels out, leaving how many moles of H2O there are.
