6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
2,50 moles of silicon contain 15,055352142.10e23 atoms.
3.4 mole Cu (6.022 X 10^23/1mol Cu ) = 2.047 X 10^23 atoms of copper.
2,89 moles of aluminium contain 17,40398707673.1023 atoms.
6,35 moles of S contain 38,24059444195.10e23 sulfur atoms.
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.
Since propane has the formula C3H8, each mole of propane will have 8 moles of hydrogen atoms, so 5 moles of propane will contain 5x8=40 moles of hydrogen.
0,2 moles contain approx. 1,2.10e+23 atoms, molecules etc.
2.6 moles C9H8O4 (9 moles C/1 mole C9H8O4)(6.022 X 10^23/ 1mole C) = 1.4 X 10^25 atoms of carbon
