How many moles are in a 63.60 g sample of carbon? (the molar mass of carbon is 12.01 g/mol.)

5.29 moles

Explanation:

In order to calculate this you just have to divide the grams of the element that there are by the grams of that given atom that make uo for a mol, in this case for carbon 12.01 grams make up a mol, so we just have to divide the gram that we have by 12.01 grams:

So we know that there are 5.29 moles in 63.6 grams of carbon.
