I don't know what "q.s" is but I assume you want a total volume of 120 mL of a solution having a strength of 10 mg/mL, so you need 1200 mg of the active ingredient, or 12 x 100 mg tablets.

If this is homework, fine. If you will be actually dosing someone, please check with a qualified person. I am NOT a pharmacy tech.

This order has a problem. The dr's order does not say how much actual dosage of the medicine to give. It just says 120 ml as the given volume amount.
