Answer:

#"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"#..
