A mass of an iron block has a mass of 21.78⋅g. What is its density if its volume is 1.5⋅mL? Chemistry 1 Answer anor277 Oct 25, 2017 ρdensity≅15⋅g⋅mL−1 Explanation: By definition, ρdensity, is the mass per unit volume, and thus we take the quotient.... ρ=massvolume.... ρFe=21.78⋅g1.5⋅mL=??⋅g⋅mL−1 By the way, ρFe is actually approx. 8⋅g⋅mL−1....so your question quotes erroneous data.....
