Twenty milligrams of drug y is injected intravenously. one hour after the injection, blood is collected and assayed for the concentration of drug y. if the concentration of drug y in this specimen was 0.4 mg/l, what is the volume of the distribution for this drug?

The volume of the distribution for this drug is 50 L

Step-by-step explanation:

Data provided in the question;

Amount of Drug Y injected = 20 milligrams

Concentration of drug Y = 0.4 mg/L

Now,

The concentration is given as:

concentration =

Thus,

0.4 mg/L =  

or

Volume of solution =

or

Volume of solution = 50 L

Hence,

The volume of the distribution for this drug is 50 L

step-by-step explanation:

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
