Answer : The volume of compound B needed are, 430 mL
Explanation :
As we are given that:
There are 6 milliliters of compound A used for every 5 milliliters of compound B. That means,
Volume of compound A = 6 mL
Volume of compound B = 5 mL
Total volume = Volume of compound A + Volume of compound B
Total volume = 6 mL + 5 mL = 11 mL
Now we have to calculate the volume of compound B needed to make 946 mL of the drug.
As, 11 mL of drug needed 5 mL of compound B
So, 946 mL of drug needed [tex]\frac{5}{11}\times 946=430mL[/tex] of compound B
And the volume of compound A needed = 946 mL - 430 mL = 516 mL
Therefore, the volume of compound B needed to make 946 mL of the drug is, 430 mL
