How many number of atom in 32 gram of oxygen?

Answer 1

Oxygen in the form O2 has a molar mass of 31.9988 gmol-1. In one gram there will be 1/31.9988 mol = 0.0313 mol. One mole of O2 equals 6.022 x 1023 molecules of oxygen, and thereby 1.88 x 1022 molecules of O2 in 1 gram. Since O2 is diatomic there are twice as many atoms as there are molecules and the final calculation to determine the number if atoms is 1.88 x 1022 * 2 = 3.76 x 1022 atoms of oxygen.

Answer 2

To determine the number of atoms in 32 grams of oxygen, one needs to know that there are 6.02x10^23 atoms per mole of any element. For elemental oxygen, the Atomic Mass is 16, so..

6.02x10^23 atoms/mole x 1 mole/16 grams x 32 grams = 1.2x10^24 atoms. If you want to know atoms in 32 grams of diatomic oxygen gas (O2), then it will be 6.02x10^23 atoms/mole x 1 mole/32 grams x 32 grams = 6.02x10^23 atoms.

Answer 3

16.00 g (6.02 x 1023 at / 16.00 g) = 6.02 x 1023atoms

Answer 4

Since Sulphur has an atomic weight of 32.07 g/mol, you have one mole of Suplhur in 32g of the stuff.

Answer 5

32 g (6.02 x 1023 atoms) / (15.99 g) = 1.20 x 1024atoms O

Answer 6

If the oxygen is present as oxygen atoms there are 2 moles. If the oxygen is present as oxygen molecules you have one mole.

Answer 7

2 atom-grams

Answer 8

2 mol
