A solution is made by adding 29.3 mL of concentrated phosphoric acid (85.5 wt% density 1.70 g/mL.) to some water in a volumetric flask, and then adding water to the mark to make exactly 250 mL of solution Calculate the concentration of this solution in molarity. TH,PO,1 = Determine the concentrations of BaBrz, Ba2+, and Br in a solution prepared by dissolving 1.75 x 10g BaBry in 2.25 L of water. Express all three concentrations in molarity, Additionally, express the concentrations of the ionic species in parts per million (ppm). BaBr, I = M Ba?+1 = M Ba?+1 = ppm [Br] = M M (Br" = pom
