. What is the mass of one molecule of oxygen

A: 5.31 × 10^-23g

B: 5.33 × 10^23g

C: 5.25 × 10^23g

D: 5.02 × 10^-23g

Best Answer

Explanation:

1 mole of oxygen molecule = 6.022 x 10²³ molecules.

Molar mass of oxygen molecule = 32 g/mol

The mass of one molecule of oxygen = 32 g/mol / 6.022 x 10²³

= 5.31 × 10^-23 g

Final answer:

The mass of one molecule of oxygen is 5.31 × 10^-23 g.
