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

To calculate the total amount of blood in the individual's body, we need to first convert the blood volume from liters to milliliters. Next, we can calculate the total amount of cholesterol in the blood by multiplying the cholesterol level per 100 ml by the total blood volume. Finally, we can convert the total amount of cholesterol from milligrams to grams.

Step-by-step explanation:

To calculate the total amount of blood in the individual's body, we need to first convert the blood volume from liters to milliliters. There are 1000 milliliters in 1 liter, so the total blood volume is 5.2 liters x 1000 milliliters/liter = 5200 milliliters.

Next, we can calculate the total amount of cholesterol in the blood by multiplying the cholesterol level per 100 ml by the total blood volume. The individual has 242 mg of cholesterol per 100 ml of blood, so the total amount of cholesterol in the blood is 242 mg/100 ml x 5200 ml = 1,258,400 mg.

Finally, we can convert the total amount of cholesterol from milligrams to grams by dividing by 1000. So, the individual's body contains 1,258,400 mg / 1000 = 1258.4 grams of blood cholesterol.

Answer 2

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.
