GenAlex Medical, a leading manufacturer of medical laboratory equipment, is designing a new automated system that can detect normal levels of dissolved somatotropin ( to ), using a blood sample that is as small as . Calculate the minimum mass in nanograms of somatotropin that the new system must be able to detect. Be sure your answer has the correct number of significant digits.

Answer:

[tex] 2 * 10^-4 [/tex] ng

Explanation:

Given:

The minimum concentration of somatotropin that can be detected by the new system is 10μgml

volume of blood sample = 2ml

From the generalised formula, mass = volume * density

In this instance, density is equal to the concentration

Hence minimum mass = volume * concentration

= 10 * 2 = 20μg or 20000 ng

= [tex] 2 * 10^-4 [/tex] ng
