Since the experimental value is smaller than the accepted value it should be a negative error. PLS HELP? 16 answers What is it with you people that help kids cheat on their homework, on this site, without any form of recompense? 18 answers More questions How do In my individual calculation the density for Aluminum was 2.88 and Iron was 8.
