Worked example: Calculating amounts of reactants and products
WebMolecular formula: CH 4 Elements: Carbon (C) , Hydrogen (H) Molecular weight: 16.043 g/mol Molar volume: 28.958 dm³/mol CAS Registry Number (CAS RN): 74-82-8 … WebJun 21, 2024 · You have already balanced the equation, so we can get the stoichiometric coefficients. From the equation we can say that 1 mole $\ce{CH4}$ gives 2 moles of $\ce{H2O}$ because their coefficients are 1 and 2, correspondigly. So 2.5 moles of $\ce{CH4}$ would give 5 moles of $\ce{H2O}$, that is $\pu{90 g}$ of $\ce{H2O}$.
