Kratek odgovor
0.50 mol contains 3.01107038 × 10^23 specified entities because the Avogadro constant is exact.
Kaj se v resnici dogaja?
Znanost si lažje zapomnimo, ko definicijo povežemo z nečim merljivim ali opazljivim.
For 2 H2 + O2 → 2 H2O, two moles of hydrogen react with one mole of oxygen in the balanced ideal ratio.
