CHEM101: General Chemistry I

Watch this video for a worked example of how to calculate molar mass and number of moles. "The molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance."
