Answer;
-The most accurate measurement is made by ;
C. Dr. Smith, who measures 13.54 g/mL.
Step-by-step explanation;
-The absolute density (how much a given volume of the substance weighs) of mercury is 13593 kilograms per cubic meter. It can also be stated as 13.56 g/cm^3. Accuracy measures the nearness of a calculation to the true value.
-In this case; the measurement by Dr. Smith is near the true value 13.56 g/cm^3, as compared to the measurements by other scientists.That is Dr. Chopra, who measures 13.487 g/mL. Dr. Thompson, who measures 13.5 g/mL. and Dr. Tyler, who measures 13.9336 g/mL.
