What is the molar mass of O2?

You figure it out by looking at the atomic mass (usually at the top, with decimals)
But for O2 (with TWO O's) you would double the 16, so O=32g/mol

The molar mass of O2 is 32 g/mol.
You should note (in light of the wrong responses above) that the atomic molar mass of Oxygen, O (not O2) is 16 g/mol.
Don't be confused.

in periodic table you will actually see 16g/mol because it is O
O2 has Two O's therefore O2=32g/mol

31.9988 g/mol because there are two oxygens
