An iv solution containing 1000 mg of aminophylline in 1000 ml of solution will completely infuse in 24 hours. how many mg of aminophylline is being infused per hour?

An iv solution containing 1000 mg of aminophylline in 1000 ml of solution will completely infuse in 24 hours. You can write the rate as either 1000mg/24hour or 1000ml/24 hour.
You are asked how many mg aminophylline infused per hour. To find it you just need to divide the rate and makes the denominator become 1 hour.

The calculation would be: 1000mg/24hour = 41.66 mg/1 hour

Yeah, but what are you trying to ask?
