Molar Mass and Atomic Mass Concepts

The video tutorial explains how to calculate the molar mass of nickel(II) chloride hexahydrate (NiCl2.6H2O). It begins by identifying the molar masses of nickel and chlorine from the periodic table. The tutorial then calculates the molar mass of the six water molecules associated with the compound. Finally, it sums up these values to find the total molar mass of NiCl2.6H2O, which is 237.71 grams per mole. The video concludes with a brief summary of the calculation process.
