1. What mass of NaCl is needed to prepare 5000 vaccine doses? 2. Find the concentration of the vaccine diluent in terms of molarity. A vial of vaccine has an unknown mass of vaccine dose. It was reconstituted with the diluent to 10 mL. Then, a 50 μL aliquot was obtained from this solution, then transferred to another vial. After that, it was diluted to 2 mL. Then, another 1 mL aliquot was taken and diluted to 1.8 mL. Lastly, the 1.8mL had enough vaccine for six doses of 30 μg of vaccine. 3. How many mg of vaccine is in the first vial?
A vaccine uses 0.9% (w/v) NaCl as diluent. To be administered, the vaccine must be diluted to a total volume of 1.80 mL, and each vial can be used to administer 6 doses. (6 doses = 1 vial)
