how much pure calcium carbonate (100.09 g/mol) is required to produce
To produce 24.1 mL of carbon dioxide gas, approximately 107.25 g of pure calcium carbonate is required. Explanation: To calculate the amount of pure calcium carbonate (CaCO3) required to produce 24.1 mL of carbon dioxide (CO2) gas, we need to use stoichiometry. We'll use the balanced chemical equation: CaCO3 + 2 HCl → CaCl2 + CO2 + H2O

How to Make Eggshell Calcium (and Why You'd Want to)
Robert makes an excellent point here! Just try soaking a hard boiled egg in vinegar overnight. This will extract all of the calcium from the shell (1 shell is about 2000mg calcium). The vinegar causes the carbonate to be separated from the calcium. The carbonate evaporates as bubbles, and the calcium is left in the vinegar.
