You calculate the density of the block of aluminum to be 2.68 g/cm3. Continuing the example, if the reference value for the density of the liquid in Step 1 is 1.2 g/mL, then the error is 16.7% [(1.4 g/mL -- 1.2 g/mL) ÷ 1.2 Add your answer Source Submit Cancel Report Abuse I think this question violates the Community Guidelines Chat or rant, adult content, spam, insulting other members,show more I think this question violates Percent Error Worksheet Ready to improve your skills in Percent-Error?
