Molar Mass and Atomic Structure

The video tutorial explains how to calculate the molar mass of glucose (C6H12O6). It begins by identifying the atomic masses of carbon, hydrogen, and oxygen from the periodic table. The tutorial then demonstrates how to multiply these atomic masses by the number of each type of atom in glucose and sum them to find the total molar mass. The final result is that one mole of glucose equals 180.16 grams. The video concludes with a brief summary of the calculation process.
