Answer:

425 mm


Step-by-step explanation:

The ratio of compound A to compound B is 5 is to 6.

So, we can say that the total ratio is of 11 parts (5+6=11).

If the chemist wants a total of 935 mm of the drug, then each of the 11 parts are worth:

[tex]\frac{935}{11}=85[/tex]


From the ratio, we know that Compound A is 5 parts. So:

[tex]85*5=425[/tex]

425 mm of Compound A is needed.
