Students in Mr. Klein's chemistry class are conducting an experiment to calculate the specific heat of a copper sample. Mr.
Klein 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/gºC, which of the following lab
teams have an unresolved problem on their hands?
team 1: calculates 0.390 J/gºC
b team 2: calculates 0.395 J/gºC
both teams
d neither team
C
