A student enters the lab, obtains an unknown solid object from the Stockroom window, and conducts Part A and B1 of the Experimental Procedure. The student performs 3 independent trials. Using their measurements, the following densities are calculated for the unknown solid:

Density from Trial 1 = 7.31 g/cm3


Density from Trial 2 = 6.55 g/cm3


Density from Trial 3 = 7.28 g/cm3


Calculate the average deviation for these densities, report your answer to the correct # of significant figures.

Answer 1

Dear student,
