## How much does 1 mole of air weigh?

28.9647 g/mol

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

**How do you calculate moles of gas?**

Use the mass of the hydrogen gas to calculate the gas moles directly; divide the hydrogen weight by its molar mass of 2 g/mole. For example, 250 grams (g) of the hydrogen gas corresponds to 250 g / 2 g/mole = 125 moles.

### How many moles are there in air?

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

**How many moles are in oxygen?**

One mole of oxygen gas, which has the formula O2, has a mass of 32 g and contains 6.02 X 1023 molecules of oxygen but 12.04 X 1023 (2 X 6.02 X 1023) atoms, because each molecule of oxygen contains two oxygen atoms.

## How do you calculate 1 mole of oxygen?

Complete step-by-step answer: Here, it is given that: 16 g of oxygen contains 1 mole of oxygen atoms. In simple terms we can say that: mass of 1 mole oxygen atom (W) = 16 g / mol.

**Is O2 16 or 32?**

O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu.
