The Atomic Mass of sodium is 22.989, so that 64 grams of it contain 64/22.989 = 2.8 moles, to the justified number of significant digits. The number of particles in a mole of atoms is known as Avogadro's number and is about 6.022 X 1023. Therefore, the sodium contains 1.7 X 1024 and the nitrogen contain 1.8 X 1024.

How many moles of nitrogen are contained in 1.61 x 10 atoms of nitrogen?
To find the number of moles of nitrogen in (1.61 \times 10^{24}) atoms, you can use Avogadro's number, which is approximately (6.022 \times 10^{23}) atoms per mole. Calculating the moles: [ \text{Moles of nitrogen} = \frac{1.61 \times 10^{24} \text{ atoms}}{6.022 \times 10^{23} \text{ atoms/mole}} \approx 2.68 \text{ moles} ] Thus, there are approximately 2.68 moles of nitrogen in (1.61 \times 10^{24}) atoms.
How many grams of Nitrogen in 76.0 moles of Na2 Cl?
There are two nitrogen atoms in one formula unit of Na2Cl. The molar mass of nitrogen is approximately 14.01 g/mol. Therefore, the total mass of nitrogen in 76.0 moles of Na2Cl is 76.0 moles x (2 nitrogen atoms / 1 formula unit) x (14.01 g/mol) = 2121.52 g.
How many moles of nitrogen are in 4.561 gram of nitrogen?
4.561 / 28 = 0.163 moles of nitrogen.
How many moles are in X molecules of NO 2?
1.5 moles of N2O5 Each molecule of NO3 contains one atom of nitrogen, so 3 moles of the compound will contain 3 moles of N atoms. However, N2O5 molecules each contain two nitrogen atoms, so each mole of N2O5 has two moles of nitrogen. So, in order to have three moles of N atoms, you need only 3/2 = 1.5 moles of N2O5.
