How many moles of oxygen are in air?

At standard conditions, one liter of air, 0.21 L of oxygen gas, contains 0.0094 moles of O2.

How many moles of oxygen are in 1 mole of air?

So, we can now say the number of moles of oxygen in 1 L of air containing 21% oxygen by volume, in standard conditions, is 0.0093 mol.

How much is a mole of air?

The molar mass of dry air is 28.9647 g/mol.

How many moles is 1l air?

As long as the gas is ideal, 1 mole = 22.4L. You can double check this with our numbers.

What is the mole of oxygen?
