2. The Anemovax COVID-19 vaccine uses 0.950% (w/v) NaCl (normal saline, preservative- free) as its diluent. After removing from the freezer or refrigerator, the vaccine must be mixed with the diluent before administration. It is diluted to a total volume of 10.0 mL, and each vial contains eight doses. a. Calculate the mass (in grams) of NaCl that is needed in order to prepare a total of 10,000 doses of the vaccine. b. Express the concentration of the vaccine diluent in molarity. (MW = 58.44 g/mol) One vial of Anovax vaccine contains an unknown mass of vaccine dose. It was diluted to 20.0 mL. A 25.0-µL aliquot was taken and was further diluted to 2.00 mL. Another 1.00- mL aliquot was taken and was diluted to 1.8 mL. Finally, this 1.8mL was found to have enough vaccine for five 20-ug doses of vaccine. c.
