WebbStarting with 0.016 moles of Aluminum, you theoretically can make at most 0.016 moles of Alum. Multiply 0.016by the molar mass of Alum and that's your theoretical yield. Hope this helps! Reply Wierd657 • Additional comment actions I got 7.913g of Alum as my answer, which I feel is correct. Thanks a bunch. WebbWe know this is a 1-1 molar ratio. So for one mole of aluminum, We have one mole of alum. So then we know that one mole Alam has a massive alum that is 4 74.44. So we're gonna go for 74.44 times .315, Divide that by 26.98. And when we do that, we get a theoretical yield of 5.54 g of alum decomposed To produce .315 g of aluminum. baku mutu udara emisi sumber tidak bergerak
