Answer:
The correct answer is: the mass in grams of one mole of a substance
Explanation:
The molar mass of a given substance corresponds to the mass of one mole of this in grams. Corresponds to a physical property of the substance. Example: the molar mass of water (H20) is:
Molar mass H20 = (Mass H) x 2 + Mass 0 = 2 x 1 g + 16 g = 18 g / mol
