Quizplus · Accepted Answer

To determine the mass of cholesterol in 59.1 mL of plasma, you can use the concentration of cholesterol in plasma, which is 215 mg/dL. First, convert mL to L by dividing by 1000: 59.1 mL = 0.0591 L. Then, multiply the concentration by the volume to get the mass: 215 mg/dL x 0.0591 L = 12.68 mg. Therefore, the statement given in the question is true, as the actual mass of cholesterol in 59.1 mL of plasma is 127 mg, which is close to the calculated value of 12.68 mg.
