Astudent reports three trials to measure the density of an unknown metal. the percent error in these trails is given in the table

Hi!

Let me complete the question for you. 

Trial Count  Percent Error

    Trial 1               0,05

    Trial 2              0,02

    Trial 3               0,01

The most accurate value is the one From Trial 3

Percent Error is a measure of the difference between the experimental value and a theoretical one. The equation for calculating the percent error is shown below:



Results are more accurate as the Percent Error is lower, so as Trial 3 has the lowest percentage error, the result of it would be the most accurate.

Have a nice day!

The correct answer is "atomic weight".
