Explanation:
The molecular mass of oxygen (O
2
) is 32 grams.
∴ 6.023×10
23
molecules of oxygen (O
2
) have mass =32 grams.
∴ One molecule of oxygen (O
2
) will have mass =
6.023×10
23
32
=5.31×10
−23
grams.
Final Answer: One molecule of oxygen (O
2
) have mass =5.31×10
−23
grams. Hence option A is correct.
