calculating percentage of caco3 in a limestone sample

2018-9-20  2. Use the balanced equation to work out the ratio of CaCO3: CO2 and therefore the number of moles of CaCO3 used. 3. Calculate the mass of CaCO3 used (by doing moles x molecular mass found from periodic table) 4. Calculate the percentage of CaCO3 by doing (mass of CaCO3 from step 3)/ (mass of limestone sample) x 100%.
