    Orderd: 0.1mcg/100mL
    Have: 25mg/hour

    You need to convert Micrograms to Milligrams, so you Multiply by 1000.

    0.1x1000= 100mg (Conversion Factor)

    100mg x 100mL= 10,000

    10,000 (divided by) 25mg= 400

    Thus your answer is 400mL/hr

    I am unsure if your searching for mg/hr or mL/hour nevertheless here are my calculations.
