Answer:
2 mL
Step-by-step explanation:
Given:
Volume of water for injection = 23 mL
Resulting concentration = 200,000 units per mL
Amount of drug in the vial = 5,000,000 units
Now,
Let the final volume of the solution be 'x' mL
Now, concentration = 
thus,
200,000 = 
or
x = 25 mL
also,
Total volume 'x' = volume of water + volume of powder
or
25 mL = 23 + volume of powder
or
Volume of powder = 2 mL
3k-1=7k+2
+1 +1
3k=7k+3
-7k -7k
-4k=3
divide each side by -4
/-4 /-4
k=-3/4
or
k=-.75
