Question

Medal
A pharmacist receives an IV order from a doctor for 50 mg of cefaclor. The label on the bottle of cefaclor has a concentration of 25 mg of drug per 250 mL of liquid. How many mL of the liquid should the pharmacist prepare for the IV?
? mL

Answer 1

there is \[\frac{ \text {25 mg of drug} }{\text{ 250 ml of liquid } }\]
So using the same proportions How man ml of liquid would we need for 50 mg of the drug
Notice that 25*2=50

Answer 2

so the answer is 5?

Answer 3

How did you get 5?

Answer 4

25 / 250= 0.1 * 50 = 5

Answer 5

25/250=.1
Means that 10% of the mixture is drugs
so that means 50/x=.1
Makes no difference how many mg of drug we have we will always have the same propotion. 10% of the mixture will be drugs and 90% will be liquid
Solve for x
50/x=.1

Answer 6

so then answer is 1?

Answer 7

no

Answer 8

\[\frac{50}{x}=.1\]
Solve for x
