# How many moles are present in O2?

Contents

1 Answer. Mole is a number that connects mass of a substance with its number of particles. 2500 g of O2 = 1/32 x 2500 = 78.125 moles.

## How many moles are in O2?

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 moles are in 4 Oxygens?

Since oxygen has an atomic mass of 16 g/mole, the molar mass of oxygen gas (O2) is 2 x 16 g/mole = 32 g/mole. Since 1 mole of oxygen is equivalent to 32 g, 4 moles of oxygen gas would be equivalent to 4 moles x 32 g/mole = 128 g. Thus, 4 moles of oxygen gas (O2) would have a mass of 128 g.

## How many moles are in 5g of O2?

Consequently, how many moles are in 5g of o2? The answer is 0.031251171918947. We assume you are converting between moles O2 and gram.
