Calculate the molar mass of CH4

Explanation:

The molar mass of a compound is given as the product of summation of relative masses of constituent units and the molar mass constant.

Molar mass of element = Relative atomic mass x molar mass constant (1g/mol)

Thus, molar mass of a compound = sum of molar masses oa all consitutent atoms

we know,

Molar mass of C = 12 g/mol

Molar mass of H = 1g/mol

Thus, molar mass of methane (CH4) = [ 12 + 4(1)]g/mol

16 g/mol

Final Answer: The molar mass of methane is 16 g/mol.
