    NO.....If you have 3 cc of solution that has 1000mg of medicine in it.......how much medicine(how many miligrams) would be in each 1cc.

    So you have

    1000mg
    3cc

    and you want to know how many X? mg per 1 cc

    X? mg
    1cc

    How many mg do you have per 1 cc?

    1000 divided by 3 equals........

    it says your final volume is 3ml. you have 1000mg in 3ml. therefore each ml has 333.3mg in it. you got it right in post #6.

    in cases like this i always suggest drawing a picture to help you visualize your problem. or take 1000 pennies, ten bucks (in your imagination), and divide that by 3-- $3.33.

    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?
    Who came up with this question? I would overthink that one because I have never seen powder measured in mL's. The vial usually says to reconstitute with a certain amount of sterile water or NS.
