WebNov 6, 2015 · Explanation: In 1 formula unit of Al(N O3)3, there are (clearly!) 9 atoms of oxygen, 3 nitrogen atoms, and 1 aluminum atom. I have gone on before that the mole ( N A, Avogadro's number) is simply a much larger number, i.e. N A = 6.022 × 1023. So, in 1 mole of Al(N O3)3 there are (9 × N A) O atoms precisely. What is the mass of 1 mol Al(N O3)3? WebThey can be atoms, formula units (of ionic compounds), or molecules. That information still needs to be specified. Because 1 H 2 molecule contains 2 H atoms, 1 mol of H 2 …
