The number of entities in a particular quantity of chemical substance is known as its amount. This amount can be expressed as a mole, which is a standardized unit, and is related to the mass of that substance through Avogadro’s number and the molar mass. The molar mass of a substance is the mass per mole of that substance, and is a characteristic property of the substance. For aluminum, the molar mass is approximately 26.98 grams per mole, meaning that one mole of aluminum has a mass of 26.98 grams.
