Avogadro's Number, The Mole & Molar Mass

  • This video conceptualizes the definition of a mole of a substance as being equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions). The number 6.022 × 10²³ is known as Avogadro's number.

  • This video explains the concept of moles and how it relates to mass in grams by the molar mass of a compound. It also explains how moles relate to atoms and molecules through Avogadro's number.

  • This video focuses on Avogadro's number and how it is used to convert moles to atoms. This video also explains how to calculate the molar mass of a compound, and how to convert from grams to moles.

  • This study guide explains the concept of a mole, and provides examples of calculating the molar mass of: Al(NO3)3, Ba(SCN)2, CO, N2, Ar, HCl, CaSO412H2O, Ca(C2H3O2)2, (HOOCCH2)2NCH2CH2N(CH2COOH)2, and nitrogen.

  • This video explains how to calculate the molar mass of a compound, which is helpful especially in mole to gram conversions, in three easy steps.

  • This video explains how to calculate the molar mass of a compound, and provides various examples to find the molar mass of chemical compounds.
