Question

If you take a 14.0-mL portion of the stock solution and dilute it to a total volume of 0.700L , what will be the concentration of the final solution?

Answer 1

You're going from 14 mL to 700 mL, a 50-fold increase in volume. Therefore, the final concentration would be 50 times less than what you started with in your stock solution. You don't give a concentration in you question though...
