# What is the mass of one mole of 02?

Contents

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.

## What is the mass of one O2?

O2 is a diatomic molecule. The mass of an oxygen atom = 16 amu. ∴ Mass of O2 molecule = 2 × 16 = 32 amu. ⇒ 5.31 × 1023g.

## What is the mass of 1 mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.

## How many grams are in 1 mole of oxygen?

For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains 6.022 × 1023 oxygen atoms. Similarly, for one gram atomic weight of silicon with atomic weight of 28 grams, one mole of silicon still contains 6.022 × 1023 silicon atoms.

## What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## How much mass does 1 mole of O2 gas have apex?

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 many molecules does 1 mole of O2 gas have?

Originally Answered: What will be the number of oxygen atoms in 1 mole of O2? A mole is 6.023E23 of whatever you are counting. A mole of O2 molecules has 6.023E23 molecules, and each molecule is made up is two atoms of oxygen. That means that there are two moles of oxygen atoms in a mole of O2, or 1.2046E24 of them.

## What is the molar mass of P?
