A pharmacist weighs a 500-milligram capsule of ampicillin and finds that it weighs 3/20 of an ounce. How much would 50 capsules containing 250 mg weigh?
For a pharmacist dispensing pills or capsules, it is often easier to weigh the medication to be dispensed rather than to count the individual pills. If a single antibiotic capsule weighs $0.65 \mathrm{g},$ and a pharmacist weighs out 15.6 $\mathrm{g}$ of capsules, how many capsules have been dispensed?
