Got a Periodic Table?

Explanation:

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

$(12.011 + 4 \times 1.00794) \cdot g \cdot m o l^{- 1} = ? ? \cdot g \cdot m o l^{- 1}$ $(12.011+4xx1.00794)*g*mol^-1=??*g*mol^-1$ .

approximately 16 grams/mole

Explanation:

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

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

Adding $12 + 4 = 16$ $12 + 4 = 16$
