Question

the gram molecular mass of O2 molecule is_________​

Answer 1

Answer:

32 g/mol

The molar mass of oxygen is 16.00 g/mol. The molar mass of molecular oxygen O2 is 32 g/mol.

Answer 2

Explanation:

32 g of oxygen = one mole of oxygen = 6.022 × 10²³ molecules of oxygen. So for the molecular oxygen or diatomic oxygen O₂: 2 × 16 g/mol
