GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect borderline high levels of dissolved cholesterol (170, to 200. mg/dL), using a blood sample that is as small as 250 μL Calculate the minimum mass in milligrams of cholesterol that the new system must be able to detect Be sure your answer has the correct number of significant digits.

Explanation:

Range of the equipment to detect cholesterol in blood = 170.0  to 200.0 mg/dL

Minimum amount of cholesterol that can be detected by instrument = 170 mg/dL

Volume of blood sample = 250 μL= 0.0025 dL (1 dL = 100000 μL)

Amount of dissolved cholesterol in 250 μL sample of blood =

170 mg/dL * 0.0025 dL =  0.425 mg

The minimum mass of cholesterol that the new system must be able to detect is 0.43 milligrams.
