Calcium peroxytoctahydrate is synthesized according to the following reaction. During the synthesis based on 3.5 g calcium carbonate, 7.5 mL of 18% HCl with a density of 1.19 and 5.5 mL of 25% NH3 with a density of 0.91 were used, and further hydrogen peroxide and excess water were added to the medium. Since 2.35 g of calcium peroxytoctahydrate is obtained in this way, what is the% yield of the experiment? (HCl: 36.5 g/mol; NH3: 17 g/mol; CaCO3: 100 g/mol; CaO2.8H2O: 216 g/mol) CaCO3 + 2HCl  2NH3 + H2O2 + 7H2O   →  CaO2.8H2O +  CO2  + 2NH4+ + 2 Cl-
