One mole of sodium weighs more than one mole of oxygen. This is because sodium has a larger atomic mass than oxygen.
One mole of hydrogen molecules (H2) contains 2 hydrogen atoms per molecule, while one mole of hydrogen atoms contains single hydrogen atoms. Since the mass of a hydrogen atom is approximately half the mass of a hydrogen molecule, the molar mass of hydrogen molecules is higher than the molar mass of hydrogen atoms.
The molar mass of oxygen is approximately 16 grams per mole. This means that the mass of 1 mole of oxygen atoms is 16 grams.

The molar mass is expressed in grams.
No, the (molar) mass (ie. the mass of one mole) is different by factor 2.004:Oxygen atom (O)15.999 g/mole O2,Oxygen molecule (elemental gas, O2) 31.998 g/mole O2Sulfur atom (S) 32.06 g/mole S,Sulfur molecule (bright yellow solid, S8) 256.48 g/mole S8,Sulfur molecule (S2) 64.12 g/mole S2 (there are more than 20 other allotropes)
Well, 1 molecule of water is made up of 2 hydrogens and 1 oxygen. And it is not possible to have 1/2 a molecule of water, therefore, you have to have at least 1 complete oxygen in there, not 1/2.

There are three moles of oxygen atoms in one mole of calcium carbonate (CaCO3). This is because there are three oxygen atoms in each molecule of calcium carbonate.
If the MgSO4 is the only oxygen containing compound in the salt, there must be four moles of oxygen atoms, and the number of atoms in 4 moles is 4 multiplied by Avogadro's number or about 2.409 X 1024 atoms.
The molar mass is expressed in grams.
To find the mass of 3 moles of oxygen atoms, you need to know the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams per mole. So, for 3 moles of oxygen atoms, the mass would be 3 moles x 16 grams/mole = 48 grams.
