SOLVED:A sample of limestone (containing calcium carbonate
In the limestone. We need to calculate the mass of calcium carbonate from the amount of calcium oxalate that was created. We'll start with the mass of calcium oxalate in milligrams and convert the milligrams into grams by divided by 1000. Then we have grams calcium oxalate. We can divide by its smaller mass to get moles calcium oxalate.
