  4. Check your results with Omni Calculator.

How do you calculate moles reacted?

Divide Grams by Grams per Mole

Divide the number of grams of each reactant by the number of grams per mole for that reactant. 50.0 g of Na are used in this reaction, and there are 22.990 g/mol. 50.0 ÷ 22.990 = 2.1749. 2.1749 moles of Na are used in this reaction.

How do you find the moles of oxygen?

So, guys, in one mole of oxygen, how many grams are there if you take a look at the product table? Or maybe you remember the atomic weight of oxygen. It is 16 g per one mole, right, so 16 g per one more. So all you have to do is divide 35.2 by 16 and that will give you the answer in moles to to moles of oxygen atoms.
