=2.5×16= 40g. `

## How many moles of oxygen are in 5 grams of O2?

As we know 1 mole of O2=32gm,as theatomic mass of O2=16amu so the mol mass and the molecular mass is equals to 32amu…means 32gm…as per question 5 mole so directly multiplying we can get our answer that is 160 gm… When you say oxygen , O2 is considered. So , 5 moles of O2 will be 16 × 5 = 160 gms ….

## How many grams of O2 are in 1 mole of 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 grams of O2 are in a 5.0 mol of the element?

Therefore, 5 moles × 32.0 g/mol = 160 grams is the mass (m) when there are 5 moles of O2 .

## How many particles are in 2 moles of oxygen?

According to the concept, 1 mole contains 6.023 ×10^23 particles. So, 2moles of O2 contains 2× 6.023×10^23 molecule= 12.046 ×10^23 molecule . Now, 1 molecule of oxygen contains 2 atoms. Hence, 2mole of O2 contains 2 ×2 ×6.023 ×10^23 atoms = 24.

## How do you find the moles of oxygen?

So, guys, in one mole of oxygen, how many grams are there if you take a look at the product table? Or maybe you remember the atomic weight of oxygen. It is 16 g per one mole, right, so 16 g per one more. So all you have to do is divide 35.2 by 16 and that will give you the answer in moles to to moles of oxygen atoms.

## How do I calculate moles?
