WebLesson Explainer: Moles. In this explainer, we will learn how to define the mole in terms of Avogadro’s constant and convert the mass of a substance to an amount of moles. In 1811, Amedeo Avogadro hypothesized that gases of equal volumes at equal temperatures and pressures contain the same number of gas particles. WebThis sheet is great for introducing or reviewing the basics of Avogadro's Number, the Mole, Molar Mass, and chemical formulas. This sheet contains a total of 36 questions and the …
