1. For the determination of the calcium content of an unknown sample by displacement titration, the 9.76 g sample containing calcium was dissolved in 25.00 mL distilled water and the unmeasured excess of Mg/EDTA solution was added to this solution. Titration of the liberated Mg2+ required 13.34 mL of 0.09560 M EDTA. a. Calculate the percentage of Ca(NO3)2 in this sample (Ca(NO3)2 = 164 g/mol).
