The solubilities of three salts in water are shown in the graph. 1000 900 Pb(NO 800 For each salt, determine how much will remain undissolved if 500 g is mixed into a liter of pure water at 40 C. One significant figure is sufficient in each answer. K.Cro 700 Solubility (g/L) 600 500 400 KCI Pb(NO) 300 200 100 KCI: 8 0 10 20 30 40 50 60 70 80 90 100 Temperature (C) K,Cr, o, 8
