Mystery Solutions Thursday, March 15, 2018 Objective: I will explain the relationship between the mass of a solution and the mass of a solute Entry Task: Suppose you wanted to determine if your tap water contains lead (II) nitrate, Pb(NO3)2, which is toxic Do you expect the mass of 100mL of pure water to be the same as that of a solution containing Pb(NO3)2? Explain your reasoning. What is the molar mass of lead (II) nitrate? What would be the mass of 0.100 mol of lead (II) nitrate?
