What is your percent error?Solution: experimental value = 8.78 g/cm3 accepted value = 8.96 g/cm3Step 1: Subtract the accepted value from the experimental value.8.96 g/cm3 - 8.78 g/cm3 = -0.18 g/cm3Step 2: Take Du kannst diese Einstellung unten ändern. In this case, the real value is 10 and the estimated value is 9. Negative Percent Error The accepted value is 65, so your percent error is 15/65 = 0.2307 = 0.2307/1 = (0.2307 × 100)/(1 × 100) = 23.07/100 = 23.07% Percent error word problem #2 A

The error comes from the measurement inaccuracy or the approximation used instead of the real data, for example use 3.14 instead of π. This will give you a decimal number. Convert the decimal number into a percentage by multiplying it by 100.
