Why is weight of 1 mole of substance equal to atomic/molecular mass …

WebTechnically, the amu is the unit that was based on oxygen-16 until 1961, when it was redefined based on carbon-12. Today, people use the phrase "atomic mass unit," but … WebThis allows us to easily relate masses at the atomic scale to masses at the macroscopic scale. To check this, look at the mass of an amu when converted to grams: 1 a m u = 1.6605 × 10 − 24 g. Now divide one gram by one mole: 1 g m o l − 1 = 1 g 6.022 × 10 23 a t o m = 1.6605 × 10 − 24 g a t o m − 1. It's the same number! draftsight 2020 tutorial pdf
