you need to do what is called a back-titration, by reacting the seashell (ground up very fine) with an acid, then titrating the solution with a base. the data can then be used to find the moles of CaCo3, and from there you can go to grams.... Find an answer to your question To determine the mass of CO2 that forms from a given mass of CaCO3, which of the following must be known? Check all that apply. … Check all that apply. … Search

**Calculate the mass percent of CaCO3 in the original**

1) CaCO 3 is an ionic compound. The formula unit mass of this compound can be calculated by simply adding the atomic masses of all the atoms in a formula unit of the compound. how to get stickers off laptop Later, if we can find out the number of mole of unreacted acid, number of mole of calcium carbonate can then be found out. The number of mole of unreacted acid can be found by titration with the following reaction: HCl(aq) + NaOH(aq) → H2O(l) + NaCl(aq) Percentage by mass of calcium carbonate in eggshell can then be calculated by the following formula: % by mass of CaCO3 = Requirements
