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

Explanation:

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

#rho="mass"/"volume"#....

#rho_"Fe"=(21.78*g)/(1.5*mL)=??*g*mL^-1#

By the way, #rho_"Fe"# is actually approx. #8*g*mL^-1#....so your question quotes erroneous data.....
