Please check the standard deviation calculator. Percent Error Calculator Percent error = (amount of error)/accepted value amount of error = 65 - 50 = 15 The accepted value is obviously the real value for the volume, which 50 So, percent 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 Thanks, You're in!
