Q. Evlaute the Percent Error?
Juan computed the density of aluminium three times.
Trial 1: 2.74 g/cm3
Trial 2: 2.68 g/cm3
Trial 3: 2.84 g/cm3
Aluminium has a solidity of 2.70 g/cm3. Determine the percent error for each trial. First compute the error for every trial by subtracting Juan's measurement from the accepted value (2.70 g/cm3).
Trial 1: error= 2.70 g/cm3 - 2.74 g/cm3= -0.04 g/cm3
Trial 2: error = 2.70 g/cm3 - 2.68 g/cm3 = 0.02 g/cm3
Trial 3: error = 2.70 g/cm3 - 2.84 g/cm3= -0.14 g/cm3
Then substitute every error as well as the accepted value into the percent error equation. Ignore the plus and minus signs.
