After removing membranes from an eggshell, the shell is dried and its mass is recorded as 5.613 g. The egg is transferred to a 250 mL beaker and dissolved in 25 mL of 6 M HCL. After filtering, the solution containing the dissolved eggshell is diluted to 250 mL in a volumetric flask. A 10.00 mL aliquot is placed in 125 mL flask and buffered to a pH of 10. Titrating with 0.0500 M EDTA requires 41.11 mL to reach the end point. Determine the amount calcium in the eggshell as %w/w CaCO3.
