1 mole of O (oxygen) weighs 15. 9996 grams. By definition, 1 mole of any element is equal to its atomic weight expressed in grams. 1 mole is equal to 6.02 x 1023 atoms of that element.
1.409 moles chlorine (35.45 grams/1 mole Cl) = 49.95 grams of chlorine ==================
This is the third element Lithium: 6.94 g is the mass of 1 mole Li. The mass in grams of one mole of any element is exactly its atomic mass (in a.m.u.)
4 grams. Approximately, mass (in grams) of 1 mole of any chemical element is just the atomic mass of this element (4 - for He, 12 - for C, and so on). It follows from the definition of one mole - number of atoms in 12 g of C.
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
There are 32 grams of sulfur in a mole of that element. There are also 32 grams of oxygen in one mole of oxygen as it is found in its natural state (O2).
It is the same as the element’s atomic mass, but in grams.

It depends on the substance. If you have for example, 12 grams of Carbon-12. Then you have 1 mole of carbon 12 which is 6.02 * 1023 molecules of the element, which is equal to 12 grams. One mole of a compound or element is equal to that element's atomic mass in grams.
The molar mass of an element corresponds to the atomic mass of the element (found on the periodic table). The atomic mass of Sodium-Na is 22.990 g, which is also the molar mass of Na. So for 1 mole of Na, there are 22.990 grams of Na. If we had 3 moles of Na, then we would simply multiply the molar mass by 3.

The mass in grams of 1 mole of the compound (apex)
4 grams. Approximately, mass (in grams) of 1 mole of any chemical element is just the atomic mass of this element (4 - for He, 12 - for C, and so on). It follows from the definition of one mole - number of atoms in 12 g of C.
The mass of 1 mole of the element is used as a conversion factor to convert grams to moles
Na2SO4 10.0 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(2 mole Na/1 mole Na2SO4)(22.99 grams/1 mole Na) = 3.24 grams of sodium -------------------------------
