## How many atoms are present in 0.25 mole of oxygen?

**01×1023 atoms**.

## How many molecules are in a mole of oxygen?

One mole of oxygen gas, which has the formula O_{2}, has a mass of 32 g and contains **6.02 X 10 ^{23} molecules** of oxygen but 12.04 X 10

^{23}(2 X 6.02 X 10

^{23}) atoms, because each molecule of oxygen contains two oxygen atoms.

## How many particles does 0.25 mole have?

1 mole of an element contains 6.022*10²³ particles. Hence, 0.25 moles of an element will contain 6.022*10²³*0.25=**1.5055*10²³ particles**.

## What is the mass of 0.5 mole of water?
