What is the weight/volume percentage (w/v%) of 0.5 grams of lisinopril in 50 ml of a compounded oral solution?

A 1% lisinopril solution

Weight/volume (w/v%) is measured in grams of the ingredient/100 ml of the total product. 0.5 grams/50 ml = x/ 100 ml, x=(100 x 0.5)/50 = 1 gram 1 gram/100 ml = 1% Please note: If you think that the volume of liquid needs to be converted to grams/liter first, you are thinking of a different calculation. For this one, it remains grams/ml.

I like this App a lot. I got a few apps to prepare for PTCE but this is the best one so far! It has tests and practice questions with explanations.
