How to Calculate Total Blood Cholesterol in an Individual's Body
Question:
An individual suffering from a high cholesterol level in her blood has 248 mg of cholesterol per 100 mL of blood. If the total blood volume of the individual is 4.9 L, how many grams of total blood cholesterol does the individual's body contain?
a) 12.2 g b) 2.48 g c) 49.6 g d) 2480 g
Final answer:
Answer:
To calculate the total grams of cholesterol in the individual's body, we need to convert the blood volume to milliliters and use the given cholesterol level to find the total grams. The individual's body contains 12.2 grams of total blood cholesterol.
Explanation: To calculate the total grams of cholesterol in the individual's body, we first need to convert the blood volume from liters to milliliters. Since 1 liter is equal to 1000 milliliters, the total blood volume is 4900 mL. Next, we can use the given cholesterol level of 248 mg/100 mL to calculate the total grams of cholesterol.
248 mg/100 mL * (4900 mL / 100) = 12.2 grams
Therefore, the individual's body contains 12.2 grams of total blood cholesterol.
