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, CaSO4 ⋅ 1⁄2H2O, 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.
