Teeth are made principally from the mineral hydroxyapatite, Ca5 (PO4)3OH, which can be dissolved in acidic solution such as that produced by bacteria in the mouth: Ca5(PO4)3(OH) (s)+ 4H+(aq ) ? 5Ca2+(aq) + 3HPO42-( aq ) + H2O(l) If at certain temperature, 0.100 g of Ca5(PO4) 3OH was dissolved in 23.68 mL of acidic solution and at equilibrium, [H+] = 2.34 x 10-5 M, [Ca2+ ] = 7.40 x 10-3 M , and [HPO42-] = 5.22 x 10-3 M, what is the Kc of the reaction?
