< Question 1 of 3 > A 0.450 g sample of impure CaCO3(s) is dissolved in 50.0 mL of 0.150 M HCl(aq). The equation for the reaction is CaCO3(s) + 2 HCl(aq) → CaCl, (aq) + H2O(1) + CO2(g) The excess HCl(aq) is titrated by 8.45 mL of 0.125 M NaOH(aq). Calculate the mass percentage of CaCO,(s) in the sample. mass percentage:
