Question

1. Your lab experiment requires 30.5 g of lead (ii)nitrate to prepare 525 ml of solution. 
2. What are the concentrations of led ions and nitrate ions in the solution?
3. If the solution is mixed with 100 ml of a 0.250 M sodium phosphate solution, what is the concentration of the dissolved product sodium nitrate, and the mass of lead(ii) phosphate? 

Answer 1

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 80.7 mL left
