Question

a student determines the density of an unknown liquid by weighing a sample of known volume. The reported density is found by the instructor to be significantly higher than it should be. Which of the following experimental errors could account for this result?

A. The pipet used was filled to a level above the calibration mark.
B. The balance was read incorrectly, and the recorded sample mass was lower than the true sample mass.
or
C. A part of the sample was spilled from the beaker before it was weighed.

Explanation / Answer

Option B

Density = Mass/ volume

In this experiment volume is known. So, the error occured in measurement of mass which is less than the actual mass. In this case the measure density value will be higher.
