34 At room temperature, a student determines the density of a sample of nickel to be 9.79 g/cm3. Based on Table S, what is the student’s percent error for the density of nickel?
(1) 0.091%
(2) 0.10% (3) 9.1%
(4) 10.%
Solution: According to table S, the density of nickel is 8.90 g/cm3. Table T shows the formula for % error which is
