Question

1. Calculate the molecular masses of CH4​

Answer 1

Now, we will find the molecular mass of CH4 , the first step is to look up the atomic masses of Carbon ( C) and hydrogen (H). Next, multiply the atomic mass of each atom by the number of atoms in the compound. Hence, the molar mass of CH4 is 16 gm/mol.

Answer 2

Explanation:

mass of carbon=12u

mass of hydrogen=1u

=12+1×4

=12+4

=16u
