Web10 de ago. de 2024 · 1 mol Al = 26.98 g Al. We can divide both sides of this expression by either side to get one of two possible conversion factors: (5.4.1) 1 m o l A l 26.98 g A l a n d 26.98 g A l 1 m o l A l. The first conversion factor can be used to convert from mass to moles, and the second converts from moles to mass.
