Therefore, 160 g of oxygen is present in 5 moles.

## How many grams is 5 O2?

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

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

Moles of a Substance and the Molecular Weight

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. If we total up the gram amounts of each element in the water molecule = 15.998g/mol + 2(1.008g/mol) we get the molar mass of water = 18.014g/mol.

## How many molecules are in 5 moles O2?

Hence, number of moles of Oxygen in 5 Moles of CO = 5. The number of oxygen atoms present can be obtained by multiplying the moles of oxygen by Avogadro’s Number. So, number of oxygen atoms present = 5 x ( 6.023 x 10^23 ) = 30.115 x 10^23 nos. Best Wishes.

## How many moles are in 5 grams?

Thus, there are 0.125 mole in 5 grams of calcium. Thus, 5 grams calcium constitute 0.125 mole of calcium. In the above case, mass of element is 5 grams and molar mass of element is 40g/mol.

## How many moles is O2?

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 grams of co2 are produced from 5 moles O2?

The mass of carbon dioxide produced (to one significant figure) is 400 g.

## How many grams are in moles?

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 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 many moles are in 2 grams of oxygen?

per mole of oxygen. From here, the answer is simple. Just multiply 2 by 31.9988 g because there are two moles of oxygen.

## How many moles of oxygen are in 5 moles of water?

Since moles are just “some number of particles”, and since one O2 molecule contains enough oxygen for two H2O molecules, you need 2.5 moles of O2 for 5 moles of H2O.

## How many moles of oxygen are present in 5 moles of water?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water.
