Note: You are calculating mass which is determine the gram(g) You will have to cancel out the mol (28.97 g/mol) * mol will give grams by itself Given the mass 3.33 moles of air 28.97 g/mol * 3.33 mol = 96.47 grams Solution: 96.5 grams
8 valence electrons are found in noble gases. Since noble gases have 8 valence electrons that means they have a full shell - which makes them unreactive
