Answer 1

Answer:

1- 0,04 U/ml

2- 1mg/ml

3- 0,5 mcg/ml

4- 250 miliunits per hour.

5- 17 miliunits per minute at a 100 ml/h speed.

Explanation:

4 and 5-25 mL/h) x ((10 u)/(1000 mL)) = .250 u/h (250 miliunits per hour)

At a delivery rate of 100 mL/h, you can deliver is 1000 milliunits per hour, or about 17 milliunits per minute.
