Question

26. Percent error calculations are used to determine how close to the truevalues, or how accurate, experimental values really are. The formula issimilar to finding percent of change.Experimental Value Actual Valuelx 100Percent ErrorActual ValueIn chemistry class, Charlie records the volume of a liquid as 13.3 milliliters.The actual volume is 13.6 milliliters. What is his percent error? Round tothe nearest percent.

Answer 1

The experimental value is how much Charlie thought it was and the actual value is the actual value. Set up the problem: ((13.3-13.6)/13.6))x100. 13.3-13.6=-.3. -.3/13.6=-.022. .022x100=-2.20. The percent would be -221%...
