The mole is the atomic weight expressed in grams.
The atomic number of nitrogen (N) is 7. The atomic weight of N is 14.00674 grams per mole. Nitrogen gas exists as a diatomic molecule: N2.
you take the atomic mass of the atom (or molecule) and you have the mass in grams
The atomic mass of Boron (B) is 11 but to be more accurate, the atomic mass is 10.81.
Atomic mass ratio for O : N is 15.9994  : 14.0067 .So it takes 14.0067/15.9994 moles of Oxygen to have the same mass as one mole of nitrogen. This is valuated at 0.8754516 to 1.00000
One mole of atoms of an element is equal to the atomic mass of that element expressed in grams. Nitrogen-14 so one mole of nitrogen weighs 14 g
The atomic number of nitrogen (N) is 7. The atomic weight of N is 14.00674 grams per mole. Nitrogen gas exists as a diatomic molecule: N2.
By definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Nitrogen's atomic mass is 14.007 grams.
The mole is the atomic weight expressed in grams.
10.81g This is found by looking at the atomic weight. The atomic weight refers to the mass of a singe atom in units of AMU (atomic mass units) and it also refers to the mass of one mole of the element in grams.
The atomic weight of Hg is 200.59 grams per mole.
As a rule of thumb, the atomic mass of an element equals the number of grams of that element equals a mole. Since the atomic mass of Nitrogen is 14, there are 14 grams in one mole of Nitrogen. Next, we just have to divide 42 by 14 and we get our answer: There are 2.9988 moles in 42 grams of Nitrogen.
The weight of one mole of an element is the element's atomic mass. So Carbon for example has an atomic mass of 12. If you had one mole of Carbon you would have 12 grams of Carbon.
The atomic weight of calcium is 40,078 +/- 0,004 (IUPAC, 2005).
The atomic weight of sodium is 22.98976928 Grams per mole.
The atomic number of nitrogen (N) is 7. The atomic weight of N is 14.00674 grams per mole. Nitrogen gas exists as a diatomic molecule: N2.
In one mole of Uranium there are 238.02891g of Uranium. This number comes from its atomic weight on the Periodic Table. The mass of one mole of an element is its atomic weight in grams.
