A Student Measured the Density of Galena
Calculating Percent Error
Percent Error = |(Measured Value - True Value)| / True Value x 100%
Percent Error = |(7.6 - 7.9)| / 7.9 x 100% = 0.3 / 7.9 x 100%
Percent Error â 0.04 x 100% = 4%
Therefore, the percent error of the measurements in determining the density of Galena is approximately 4%.
