Are you sure? Question says in EACH milliliter. sounds like it should be 111 ml

so would it be 1000 divided by 3? 333.3

The second question seems to be a big problem for me because I dont know where to start. When it says the final volume is 3ml, does that mean that cefazolin is 0.5ml?

1. I subtracted 1.2ml from 10ml. Leaving 8.8ml of water. Is this right? 2. I get 0.16 ml

I am having a problem calculating reconstitution math problems. Here are two math problems that seem easy, I just do not understand the problems? 1. A vial of cefazolin contains 1.2 mL of powder. The total volume of the vial when the powder is reconstituted is 10 mL. What is the amount of sterile water needed to reconstitute the powder? 2. Cefazolin is supplied in 1 gram vials of powder which is reconstituted with 2.5 mL of NaCl for injection for a final volume of 3 mL. What is the approximate concentration of Cefazolin in each milliliter?
