    Tagamet (Cimetidine) is available in liquid form labeled 300 mg in 5 mL. 0.3 g of Tagamet has been prescribed PO. How many mL should you administer?

    Can anyone help me out here, on the practice questions it says the answer is 5mL
    But I dont see how. Can you let me know how you would figure this out?
    Thank you in advance!
    Here is how we figure these problems out using dimensional analysis.

    xml= __5ml__ x 1000mg x 0.3g = 5ml
    ~ ~~300 mg ~~~1g

    ignore the ~ marks, that is the only way I could post it and keep everything in line hope it helps!
