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.

Well, one mole is equal to Avogadro's Number, or 6.02210 x 10^23 particles. Since you are not talking about the amount of oxygen atoms in 3 moles of O2, no extra multiplication is needed to compensate for that. 3 moles x (6.02210 x 10^23) O2 molecules per mole = 1.80663 x 10^24 O2 molecules.

One mole of Water is composed of 1 mole of Oxygen and two moles of Hydrogen. 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.

So, we have a mass of 32 grams. We can also use the periodic table to determine that the Mr of oxygen is 16. So there are 2 moles of Oxygen present.

So, 1 mole of H2O2 contains 6.022 x 10^23 molecules, and 1 mole of O2 contains 6.022 x 10^23 molecules.

As it is already known, 1 mole of any substance contains 6.023×10^23 atoms. 1 mole of SO2 contains one sulfur and two oxygen molecules.

Answer and Explanation: There are 6.022×1023 6.022 × 10 23 atoms in 16 grams of oxygen.

These atoms have the same number of protons, but slightly different number of neutrons. How convenient! Looks like you have 2 moles of Water! So there are 4 moles of Hydrogen, and 2 moles of Oxygen in 2 moles of Water.

1mole of O₂ gas contains 2 x Avogadro number of atoms of oxygen. ∴ 5.6 litres of Oxygen gas contains 3 x 10²³ oxygen atoms.

One mole of oxygen contains 6.022 × 1023 molecules. 1.20 × 1022 molecules of oxygen contain = 1.20 × 1022 / 6.022 × 1023 = 0.01099 moles.
