Calculate the molar mass of methane(show work)

Explanation:

So first off, you need to have the molecular formula of methane before you do anything at all. The molecular formula of methane is CH4.

The molar mass of any substance is found by adding the masses of the individual elements.

Carbon approximately has a mass of 12 amu and Hydrogen approximately has a mass of 1 amu. So we need to add these. BUT, look at the molecular formula, we have THREE hydrogens. So your work should look similar to the following:

Carbon: 12 x 1 = 12

Hydrogen: 1 x 4 = 4

Total mass of methane: 12 + 4 = 16

So, your molar mass of methane is 16 grams
