## Question

###### You made 100.0 mL of a lead(II) nitrate solution for lab butforgot to cap it. The next lab session you noticed that there wasonly 71.3 mL left (the rest had evaporated). In addition,you forgot the initial concentration of the solution. You decide totake 2.00 mL of the solution and add an excess of a concentratedsodium chloride solution. You obtain a solid with a mass of 2.080g. What was the concentration of the original lead(II) nitratesolution?___ M
