Full formal set up.
2.88 grams Na2SO4 (1 mole Na2SO4/142.05 grams)(6.022 X 1023/1 mole Na2SO4)(1 mole Na2SO4 atoms/6.022 X 1023)
= 0.020 moles of sodium sulfate atoms

To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
There are 2.26 x 10^24 silver atoms in 3.75 moles of silver. This is calculated by multiplying Avogadro's number (6.022 x 10^23 atoms/mole) by the number of moles.
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
There are 12 carbon atoms in one molecule of sugar (C12H22O11). Therefore, in 2 moles of sugar, there would be 12 * 2 * 2 = 48 moles of carbon. To convert moles to grams, you would multiply the number of moles by the molar mass of carbon (12 g/mol), so there would be 48 * 12 = 576 grams of carbon in 2 moles of sugar.
Since ammonia has a chemical formula of NH3, it contains one mole of nitrogen and three moles of hydrogen per mole of ammonia. Therefore, 3 moles of ammonia contain 3 moles of nitrogen and 9 moles of hydrogen atoms.
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.
To find the number of moles, we need to divide the given mass of cobalt (382g) by its molar mass, which is approximately 58.93 g/mol. Therefore, 382g of cobalt contains approximately 6.48 moles of atoms.
382 g Co contain 6,482 moles.

1,638 moles contain 9,864266723766.10e23 atoms.
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.
