How many moles are there in 16grams of O2?

What is the volume of 16 grams of O2 at Stp?

Look up the atomic mass of oxygen on the periodic table. It is 16 grams but look it up so you will know how to do these problems. Since oxygen is O2, multiply 2 x 16 = 32 g for the mass of 1 mole. If the mass of 1 mole is 32 grams, what number of mols is in 16 grams?

For number 2. The volume of a mole of any gas at STP is 22.4 L.
