Acertain drug is made from only two ingredients: compound a and compound b. there are 3 millimeters of compound a used for every 5 milliliters of compound b. if a chemist wants to make 736 milliliters of the drug, how many milliliters of compound b are needed?

Let 8 milliliters of compound A and 5 milliliters of compound B be a mixture.

We can then find how many mixture is needed for 845 milliliters of the drug by dividing it by (3+5=8):

736 ÷ 8

=92

As 65 mixture is used and each mixture include 5 milliliters of compound B, we can find the amount of compound B by multiplying 92 by 5

92 x 5

=460 milliliters

Therefore the answer is 460 milliliters.

Hope it helps!
