The accepted value for the density of liquid mercury is 13.5336 g/mL. Four scientists measure the density of liquid mercury in their individual laboratories. The most accurate measurement is made by Dr. Chopra, who measures 13.487 g/mL. Dr. Thompson, who measures 13.5 g/mL. Dr. Smith, who measures 13.54 g/mL. Dr. Tyler, who measures 13.9336 g/mL.

Carley Ballard · Answer 1

The correct answer is C. Dr Smith, who measures 13.5 g/mL on e2020.

Tyrell Lutz · Answer 2

Accuracy is how close the measured value is to the accepted value.

In this case, Dr. Smith, who measured 13.5g/mL, is the closest to the accepted value, and hence is the most accurate measurement (although least precise!)
