Calculating Molar Mass of Compounds

This video tutorial explains how to calculate the molar mass of sodium bromide (NaBr). It begins by identifying the molar masses of sodium and bromine from the periodic table, which are 22.99 grams per mole and 79.9 grams per mole, respectively. The video then demonstrates how to add these values to find the total molar mass of NaBr, which is 102.89 grams per mole. The tutorial concludes with a summary of the calculation process.
