"63.9976 g"

Explanation:

One mole of oxygen is "15.9994 g", but because oxygen is a diatomic molecule, it is bonded with itself. So,

"15.9994 g" * 2 = "31.9988 g"

per mole of oxygen. From here, the answer is simple. Just multiply 2 by "31.9988 g" because there are two moles of oxygen. So, the answer is "63.9976 g"..
