The accepted density of copper is 8.96 g/cm3. A lab team measured the density of a copper sample in a lab and calculated a density of 8.40 g/cm3.
Part A: Which expression calculates the percent error for the calculated density of copper?
Part B: What is the percent error?
Select two answers: one for Part A and one for Part B.
A: 8.40 / |8.4+8.96| x 100
A: |8.40| / 8.96 x 100
A: |8.40−8.96| / 8.96 x 100
A: |8.40−8.96| / 8.40 x 100
B: 4.84%
B: 6.51%
B: 6.67%
B: 2.33%
