How many molecules of sulphuric acid can be produced from 2.45 moles of hydrogen atoms?
I don’t think you’re supposed to immediately convert the 2.45 moles directly to molecules. By looking at H2SO4, you see a ratio of 2 Hydrogens, 1 Sulfur, and 4 Oxygens. Soooooo… in order to find the amount of Hydrogen molecules in Sulfuric acid, just do a simple stoichiometry equation. For 1 mol of H2SO4, there are 2 mol of H, then just multiply by Avogrado’s number of 6.022 x 10^23 to find the number of molecules.
