You are given a 0.553 gram sample of an unknown metal carbonate. You add some of the sample to a 10.0 mL sample of 0.255 M HNO3. When you have added exactly enough sample to react with all the acid, you reweigh your remaining sample and find its mass is 0.364 grams. (a). How many moles of acid reacted with the sample (b). How many grams of sample reacted with the acid? (c). How many moles of the unknown carbonate...
