Web23 sep. 2024 · The molar mass of any substance is its atomic mass, molecular mass, or formula mass in grams per mole. The periodic table lists the atomic mass of carbon as 12.011 amu; the average molar mass of carbon—the mass of 6.022 × 10 23 carbon atoms—is therefore 12.011 g/mol: Table 2.4. 1 Molar Mass of Select Substances. WebExplanation: The molar mass of methane (CH4) is calculated by adding the molar masses of each individual atom in the molecule. 1 mole of Carbon atoms has a molar mass of 12.01 g/mol. 4 moles of Hydrogen atoms have a molar mass of 4.00 g/mol. Therefore, the molar mass of CH4 is 12.01 g/mol + 4.00 g/mol = 16.01 g/mol.
