You made 100.0 mL of a lead(II) nitrate solution for lab but forgot to cap it. The next lab session you noticed that there was only 79.5 mL left (the rest had evaporated). In addition, you forgot the initial concentration of the solution. You decide to take 2.00 mL of the solution and add an excess of a concentrated sodium chloride solution. You obtain a solid with a mass of 3.359 g. What was the concentration of the original lead(II) nitrate solution?

What mass of lead(II) nitrate is present in 20.0 mL of a solution?
Two samples of a lead(II) nitrate solutions are used. Each sample is reacted with an excess quantity of a potassium iodide solution, producing lead(II) iodide, which has a low solubility and settles to the bottom of the beaker (Figure 7.2). After the contents of the beaker are filtered and dried, the mass of lead(II) iodide is determined. The reagent bottle states the concentration of the lead(II) nitrate solution is 0.472 mol/L
