1 mole Ag = 6.022 x 1023 atoms Ag
4.4910 x 1023 atoms Ag x 1 mole Ag/6.022 x 1023 atoms Ag = 0.7468 mole Ag
4,80 moles of Fe contain 28,9062761136.10e23 atoms.
4.2 moles of CS2 contain 8,4 moles sulfur.
1. Three moles of sodium contain 18,06642387.1023 atoms. 2. The mass of three moles of sodium is 68,97 grams.
Since molecules of potassium contain only single potassium atoms, molecules of iodine contain two atoms, and moles of potassium iodide contain one atom of each element, 2.5 moles of iodine are needed to react completely with 5 moles of potassium.
The molecular formula for sulfuric acid is H2SO4. This shows that each molecule contains exactly 4 oxygen atoms. Therefore, 0.750/4 or 0.1875 moles of sulfuric acid contain 0.750 moles of oxygen atoms.
