    Answer: 100mL/hr

    Explanation:

    Volume = 38mL

    administered rate = 10mL/hr

    Mass of dopamide = 209mg

    Converting administered rate to mg/hr

    (10mL/hr / 38mL) = (209mg / 1)

    2090mL*mg / hr : 38mL = 550mg/hr

    Flow rate = (administered rate / mass) * volume

    Flow rate = [ (550mg / hr : 209mg) * 38mL]

    Flow rate = 2.6315789 hr * 38mL = 100mL/hr
