Problem
A laboratory report contains the sentence: "The density of the aluminium sample was measured to be ρ=2712.34±21.7Kgm−3, a relative uncertainty of 0.80%." Find four separate faults in this sentence, judged against the house conventions for units, rounding and the reporting of uncertainty, and rewrite the sentence correctly.
