Students in Mr. Klein’s chemistry class are conducting an experiment to calculate the specific heat of a copper sample. Mr. Klei
n requires each lab team to repeat the experiment until their percent error is 2% or less. Percent error is calculated using observed values (those students calculate from their lab results) and the true value (the accepted value based on reference). The formula for percent error is: (observed – true) x 100 true If the accepted value for the specific heat of copper is 0.385 J/g°C, which of the following lab teams have an unresolved problem on their hands? a. team 1: calculates 0.390 J/gºC b. team 2: calculates 0.395 J/gºC c. both teams d. neither team
The following lab team that has an unresolved problem on their hands is team 2 in which they calculated 0.395 J/gºC since they have higher percent error compared to the other team which only has 0.390 J/gºC. So the answer would be letter B - <span>team 2: calculates 0.395 J/gºC.</span>
