What is the mass of 1 mole of #O_2# molecules?

Answer 1

#31.9988 g#

To obtain the mass of 1 mole #O_2# molecule, you simply have to multiply it to its molecular weight which is #31.9988 g/[mol]#.

g #O_2 = 1 mol O_2 * (31.9988 g/[mol O_2])# g #O_2 = 31.9988#

The molar mass of O2 molecules (Oxygen gas) is calculated by summing the atomic masses of the constituent atoms.

Molar mass of O2 = (2 * atomic mass of O) = 2 * 16.00 g/mol = 32.00 g/mol

Therefore, the mass of 1 mole of O2 molecules is 32.00 grams.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
