What should be the infusion rate in mL per hour. With a drop factor of 10 drops per mL, calculate the infusion in drops per minute.
Calculate the mass of sodium acetate that must be added to 500.0mL of 0.200M acetic acid to form a pH = 5.00 buffer solution.
If i want to make 400.00 mL of a 0.325 M KNO3 solution, and I have a 0.840 M stock solution on hand, how much of the stock solution will I need to dilute
dilute to mark with water and mix. (You will need the extra volume of this most concentrated solution for further studies.) Record your actual standard concentrations accounting for the dilution as Cstd1, Cstd2, Cstd3, and Cstd4, respectively.
