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/g°c, which of the following lab teams have an unresolved problem on their hands? a.. team 1: calculates 0.392 j/gºc. b.. team 2: calculates 0.395 j/gºc. c.. both teams. d.. neither team
