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.
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.
16.00 g (6.02 x 1023 at / 16.00 g) = 6.02 x 1023atoms
Since Sulphur has an atomic weight of 32.07 g/mol, you have one mole of Suplhur in 32g of the stuff.
32 g (6.02 x 1023 atoms) / (15.99 g) = 1.20 x 1024atoms O
If the oxygen is present as oxygen atoms there are 2 moles. If the oxygen is present as oxygen molecules you have one mole.

Oxygen has 8 protons in the atom.
There are 8 electrons in a single neutral oxygen atom.The atomic number of oxygen is 8, because it has 8 protons in its nucleus. In an elemental, neutral, atom of oxygen the number of electrons will match the number of protons. There are 8 electrons in a neutral oxygen atom.Note that oxygen can become an ion under certain circumstances, and we need to specify the neutral atom to state how many electrons there are in oxygen.
8. When an atom becomes an ion, it gains or loses electrons. The number of protons and neutrons doesn't change. If the number of neutrons changes then the atom has changed into a different isotope.
Oxygen has 8 protons. The number of protons tell you which number the atom is in the periodic table, so you can just look at the periodic table and the element's number to find out how many protons it has.
All the oxygen isotopes, natural or artificial, has 8 protons, because th atomic number of oxygen is 8.
how many numbers of atom are present in one gram of oxygen
one gram of carbon* Avogdo's number =number of atom (many atom) one atom of carbon mean carbon have a 6 electron and 12 molar mass
Every oxygen atom has eight electrons.
Every oxygen atom has eight electrons.
Oxygen has 8 protons in the atom.
Oxygen's atomic number is 8. That means an atom of oxygen always has 8 protons. To stabilize it then, it must also have 8 electrons.
There are 8 electrons in a single neutral oxygen atom.The atomic number of oxygen is 8, because it has 8 protons in its nucleus. In an elemental, neutral, atom of oxygen the number of electrons will match the number of protons. There are 8 electrons in a neutral oxygen atom.Note that oxygen can become an ion under certain circumstances, and we need to specify the neutral atom to state how many electrons there are in oxygen.
The atomic number of an element determines how many protons are in the nucleus and therefore how many electrons are in a neutral atom of the element. The atomic number of oxygen is 8 and the carbon atom is 6.
