A student wants to make a 250 mL stock solution with a concentration of 1000 mg -N/L. The student has an unlimited amount of NaNO3 and DI water. What mass of NaNO3 is needed to make 250 mL the 1000 mg -N/L solution? Using the stock solution from the previous question, what volume of stock is needed to make a 20 L solution with a concentration of 3 mg -N/L?
