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.
