I tried to figure this one out but I don't get any of the answers listed. Here's my working out for what it's worth: 1 mole of Calcium hydroxide is 74g so 74g of calcium hydroxide reacts completely with 2 moles of nitric acid or 2 times 63 grams. If I divide 100 by 74 and multiply 63 by 2 then by the answer I get is 170g.
