O He should make 8. 75 mL of the 20% solution in 26. 25 mL of solvent.

O He should make 17. 5 mL of the 20% solution in 52. 5 mL of solvent.

Answer 1

See below

Step-by-step explanation:

5 ml per day x 14 days = 70 ml required

.20x = 70 (.05)

x = 17.5 ml of 20% needed

total solution needs to be 70 ml 70 - 17.5 = 52.5 ml of solvent
