Got a Periodic Table?

#### Explanation:

Of course you have because you are doing your chemistry homework. The atomic mass of $H = 1.00794 \cdot g$, and the atomic mass of $C = 12.011 \cdot g \cdot m o {l}^{-} 1$.

(12.011+4xx1.00794)*g*mol^-1=??*g*mol^-1.

approximately 16 grams/mole

#### Explanation:

Find the mass of all the atoms then add up the mass of all the atoms in the molecule.

$1 \times C = 1 \times 12 = 12$
$4 \times H = 4 \times 1 = 4$

Adding $12 + 4 = 16$
