A mass of an iron block has a mass of 21.78*g21.78g. What is its density if its volume is 1.5*mL1.5mL?

rho_"density"~=15*g*mL^-1ρdensity15gmL1

Explanation:

By definition, rho_"density"ρdensity, is the mass per unit volume, and thus we take the quotient....

rho="mass"/"volume"ρ=massvolume....

rho_"Fe"=(21.78*g)/(1.5*mL)=??*g*mL^-1ρFe=21.78g1.5mL=??gmL1

By the way, rho_"Fe"ρFe is actually approx. 8*g*mL^-18gmL1....so your question quotes erroneous data.....
