Question

An individual suffering from high cholesterol level in her blood has 242 mg of cholesterol per 100 ml of blood. if the total blood volume of the individual is 5.2 l how many grams of total blood does the individual's body contain?

Answer 1

242 mg of cholesterol is present in 100 mL of blood. If the total blood present in a body is 5.2 L The total body cholesterol can be calculated as follows:

First calculate concentration as follows:

C=\frac{m}{V}=\frac{242 mg}{100 mL}=\frac{242 g}{100 L}=2.42 g/L

Now, total volume is 5.2 L thus, mass will be calculated as follows:

m=C×V=2.42 g/L×5.2 L=12.584 g

Thus, the grams of blood cholesterol in human body will be 12.584 g.
