How many grams are in 2.5 moles of carbon

According to the periodic table, carbon's molar mass is 12.011 grams per mole (that's the small number under the element).  So, just multiply like this to get the



So, there are approximately 0.208 grams in 2.5 moles of carbon.

Carbon's atom mass is 12. So 1 mole of Carbon is 12 grams. We should multiply
12 by 2.5:
