HI, could someone please help solve and explain this chemistry calculation to me. Thanks! The problem is:
1.00gram of a sample of limestone was dissolved in dilute hydrochloric acid and then ammonium oxalate and ammonium hydroxide added. The precipitate of calcium oxalate was filtered and dried and found to weigh 0.448grams. Calculate the percentage calcium carbonate in the limestone.
Note:
the answer is 35% but I really need someone to SHOW how to get this because I keep getting it wrong. Thanks again!
