For one gram atomic weight of oxygen with atomic weight of 16 grams, one mole of oxygen also contains **6.022 × 10 ^{23} oxygen atoms**.

## How many atoms does oxygen 3 have?

Ozone (O3) is a triatomic, molecule, consisting of **three oxygen atoms**.

## What is K mole?

**39.10 grams** is the molar mass of one mole of K.

## How many atoms is 3 moles sodium?

3 mol Na × (6.022×10^23 atoms Na/1mol Na) = **1.807×10^24 atoms Na**.

## How many moles of atoms are in 3 moles of CO2?

1 molecule of CO2 = 1 C atom + 2 O atom. So, 3 moles of CO2 contains (3 x 2 x 6.02 x 10*23) O atoms = **3.61 x 10*24 O atoms**.
