180 mg%

Explanation:

High cholesterol level has been linked to many diseases such as heart attack. While there are many kinds of cholesterol, calculating the general concentration of cholesterol still can be a good predictor.

To know the percentage concentration of any molecules you need to change the unit of the number. Since the unit in the problem is already the same unit, we just need to change the denominator into per 100ml. The calculation will be:

7.2mg / 4ml = x/100ml

x = 1.8mg/ml * 100ml

x = 180 mg%
