Explanation / Answer

I am solving the first question, Q1 as per Chegg guidelines, post multiple question to get the remaining answers

Q1)

Mass of Patient = 130 pound

Amount of Dosage given to patient = 130 pound * 2.5 mg/pound = 325 mg

Concentration of Dose = 200 mg/mL

Volume of dose required to be given to patient = amount of dosage given to patient * concentration of dose

=> 325mg * 1mL/200mg

=> 1.625 mL
