1 mol = 6.022 times 10 to the 23.

look at the atomic weight: 1 mol of any atom is equal to the atomic weight in grams.

Carbon has atomic weight of about 12 so its 12 grams per mol. Funny enough, your quesiton asks how many atoms are in 12 grams of carbon. 12 grams = 1 mol = 6.022 times 10 to the 23.
