1. What is the molar concentration of AgNO3 in the solution when a student dissolves 0.3000 g AgNO3 (169.88 g/mol) and dilutes it to precisely 250.0 ml.
2. What is the molar concentration of the final solution when 4.23 ml 0.2225 M KOH is diluted to 250.0 ml.
3. Determine how many milliliters of 0.0200 M KCl would be required to make the 2.50 L 1.33 x 10^-4 M KCl?
4. You start with 500.0 ml Solution A, which contains KI of unknown concentration. You dilute 2.00 ml of this solution to precisely 250.0 ml (solution B). Experimental measurements show that KI solution of B is 1.23 x 10^-5 M. Explain what was the molar concentration of KI in Solution A?
