Two molecules of hydrogen react with one molecule of oxygen to produce two molecules of water. How many molecules of water are produced from 2.0 3 1023 molecules of oxygen? How many moles of water are produced from 22.5 moles of oxygen?
You would need to utilize Mole ratios found in the adjusted condition; for each mole of hydrogen utilized, 2 moles of HCl are delivered. Thusly: 10 mol H2 x 2 mol HCl/1 mol H2 = 20 mol HCL. For the second question: you would need to change over 2.0x10^23 particles of Oxygen to moles of oxygen, utilizing Avogadro's number: 2.0x10^23 particles oxygen x 1 mol oxygen/6.022x10^23 atoms oxygen = 0.33 mol Oxygen utilizing mole proportions once more: 0.66 mol H2O = 2 mol H2O/1 mol Oxygen x 0.33 mol Oxygen 45.0 mol H2O = 2 mol H2O/1 mol Oxygen x 22.5 mol Oxygen fundamentally to answer stoichiometry, you should take a gander at the adjusted condition to make sense of the mole proportions between components/mixes, and utilizing mole proportions you can change over from moles of one component/compound to moles of another component/compound
