how many moles of sulfur are present in 3.4 moles of Al2(SO4)3
Quinine is a compound made up of several elements, including carbon. To determine the exact number of moles of carbon in quinine, you would need to know the molecular formula of quinine, count the number of carbon atoms in the formula, and then calculate the moles using Avogadro's number and the molar mass of carbon.
There are 4.81 x 10^23 atoms of nitrogen in 2.50 moles of NO2. This is because each molecule of NO2 contains 1 atom of nitrogen.
There are 9.03 x 10^23 atoms of nitrogen in 1.5 moles of N2O4 because there are 2 nitrogen atoms in each molecule of N2O4 and Avogadro's number (6.022 x 10^23) tells us that 1 mole of a substance contains that many particles.
To determine the number of nitrogen molecules in 12.88g of nitrogen gas, you first need to convert grams to moles using the molar mass of nitrogen (28.02 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in that number of moles.
To find the number of moles in 10.0 g of nitrogen dioxide (NO2), you first need to find the molar mass of NO2, which is approximately 46.01 g/mol. Then, divide the given mass by the molar mass to get the number of moles. In this case, 10.0 g / 46.01 g/mol ≈ 0.22 moles of nitrogen dioxide.

The clarity of this question is not clear. I will assume grams and possibly moles as that number does not look like a number of atoms. Grams first, then moles. 4.0 X 102 grams quinine (1 moleC20H2N2O2/302.236 grams)(2 moles N/1 mole C20H2N2O2) = 2.6 moles nitrogen =============== Pretty much the same procedure if you meant moles just no dividing out a mass.
You can figure this question out by looking up quinine to find its chemical formula. The number of moles of hydrogen will be the number of hydrogen in the chemical formula. Once you see the chemical formula is C20H24N2O2 then you know that there are 24 moles of hydrogen for every one mole of quinine.
10 moles of nitrogen dioxide are needed to react with 5,0 moles of water.
The reaction of nitrogen with hydrogen to form ammonia is: N2 +3H2 = 2NH3 Therefore to make 10 moles of ammonia you need 5 moles N2 and 15 moles H2
There are 4.81 x 10^23 atoms of nitrogen in 2.50 moles of NO2. This is because each molecule of NO2 contains 1 atom of nitrogen.
4.91 mol * 6.02214129(27)×1023 / mol = 2.96 ×1024
Depends on what substance is being formed. If it's nitric oxide (NO), then 5. If it's nitrogen dioxide (NO2), then 10. If nitrate (NO3), then 15.
There are 9.03 x 10^23 atoms of nitrogen in 1.5 moles of N2O4 because there are 2 nitrogen atoms in each molecule of N2O4 and Avogadro's number (6.022 x 10^23) tells us that 1 mole of a substance contains that many particles.

At standard temperature and pressure, nitrogen exists as diatomic molecules. Therefore the number of atoms in 3.4 moles is 2 X 3.4 X Avogadro's Number, or 4.1 X 1024 atoms, to the justified number of significant digits.
