Absolute differences between each observed mass and the accepted value, divided by the accepted value, multiplied by 100%

The percentage error e% = Δm/m 100

Explanation:

The absolute error is the assessment with which measurements are made, it is given by the minimum reading value of a given instrument.

The accepted value is the value measured in an instrument. Or the one calculated by an experiment.

The percentage error is the ratio of the absolute error between the value of the average per 100

e% = Δm/m 100
