Although Thomas Jefferson came to power determined to limit the reach of the federal government, foreign affairs dominated his presidency and pushed him toward Federalist policies that greatly contrasted with his political philosophy.

Explanation:
Let the volume of the 17% solution added be x.
The final volume will be 30 ml with a concentration of 1/750.
The amount of benzalkonium present will remain constant, and is the same in the final solution as in the pharmacists solution. Considering that:
moles = concentration * volume
C₁V₁ = C₂V₂
0.17 * x = 1/750 * 30
x = 0.24 ml
The number of drops that will be added are:
25 * 0.24 = 6
6 drops will be added by the pharmacist.
