Question

calculate the molecular mass of Ch4​

Answer 1

$\huge {\textbf {\underline {\underline {ANSWER}}}}$

Molecular mass of CH4 = 12 + 1 × 4

= 12 + 4

= 16 amu

Answer 2

We know...

• mass of C=12u

• mass of H=1u

So  molecular mass of $CH_{4}$=12u+1×4u

                                                                     =16u
