Iron has a density of $7\mathrm{.}86$ g$/$cm$3$

$(1$ cm$3=1$ mL

$).$ Calculate the volume $($in dL

$)$ of a piece of iron having a mass of $3\mathrm{.}73$ kg

$.$ Note that the density is provided in different units of volume and mass than the desired units of volume $($ dL

$)$ and the given units of mass $($ kg

$).$ You will need to express the density in kg$/$dL

$(1$ cm$3=1$ mL

$)$ before calculating the volume for the piece of iron.
