An individual suffering from a high cholesterol level in her blood. if the total blood volume of the individual is 5.2 l, how many grams of total blood cholesterol does the individual's body contain

If the concentration of cholesterol is 238mg/100ml:

238 mg ==> 100ml

2380 mg (or 2.38g) ==> 1000ml (1L)

So the concentration will be 2.38 g/L of cholesterol.

if the volume is 5.2 L, the total grams of cholesterol would be :

m = C . V = 2.38g/L * 5.2 L = 12.376 grams of cholesterol.
