Solution Dilution question

Question

An order for 25mg of a oral solution is needed for a patient. You have 1000mg and a 30ml bottle to make the solution. How many ml will you need for 25mg of the finshed oral solution.

So once the solution is made, I will need to get 0.75ml out which = 25mg

 

Is that correct?

Answer 1

Assuming you will fill the 30 ml bottle with 1000 mg, work this problem as a proportion.

 

x = ml taken from the 30 ml bottle holding 1000 mg

 

(25 mg)/x = (1000 mg)/(30 ml)

 

x = (25 mg)(30 ml)/(1000 mg) = 0.75 ml

 

You answer is correct.
