I have problem and can not solve it: A piece of metallic aluminum weighing 2.50 grams is treated with 75.0 mL of sulphuric acid ( d = 1.18 g/cm3 , 24.7% H2SO4 ). After the metal is dissolved, the solution is diluted to 400mL. a) Calculate the morality of the solution with respect to the aluminum salt formed. b) Calculate the morality of the resulting solution with respect to unreacted sulphuric acid. I made a slight attempt, but got lost after it: 75ml x 1.18g = 88.5g Xg / 88.5g = .247 Xg = 21.859g of H2SO4 I actually don't even know what I am doing anymore :( I'm seeking a learning experience so that I can solve other problems as well. Please, any help would be greatly appreciated.
