WebSep 26, 2024 · Examine the formula of methane: CH₄. There is a subscript of 4 after H. There are 4 moles of hydrogen in 1 mole of methane. Multiply hydrogen's molar mass by 4 before adding carbon's. H₄: 1.008 * 4 =4.032 g/mol ; CH₄: 12.011 + 4.032 = 16.043 g/mol ; 2. Convert Grams to Moles . Now we convert grams to moles. WebA few things to consider when finding the molar mass for CH4: - make sure you have the correct chemical formula. - always include the units for molecular weight (grams/mole). - make sure you do ...
