Identify the correct statement from the following

One mole of ${\mathrm{O}}_2$molecules is equal to gram molecule weight of oxygen 32 grams Weight of one mole of ${\mathrm{H}}_2$ is known as gram molecular mass or molar mass of .Therefore, 2.016 g of ${\mathrm{H}}_2$molecules represents one mole of ${\mathrm{H}}_2$.The weight of one mol of H atoms is equal to gram atomic weight (1.008 g).

We know that there are 16g of O atoms represents one mole of oxygen atoms or $6.023 \times {10}^{23}$ atoms of atom.
