WebMar 26, 2024 · Now, we also know that the mass of a single carbon- 12 atom is exactly 12 amu, as it is an isotope. And so, mass of carbon-12 = 12 amu/atom. Combining, we have: 12 amu/atom = 12 g/mol. ⇒ 1 amu/atom = 1 g/mol. Therefore we just proved that an atomic mass unit is the same thing as grams per mole. Hope this helps! WebThe 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. Created by Sal Khan.
