Question #$5$

A student is trying to determine the density of a piece of metal. She uses a balance and finds that the mass of the piece of metal is $56\mathrm{.}72g.$ To determine the volume of the metal she fills a graduated cylinder to $31\mathrm{.}0mL$ and then drops the piece of metal into the graduated cylinder. The final volume is $38\mathrm{.}9mL.$ What is the density of the piece of metal?

Be sure to round your answer to the correct number of significant figures.

$\frac{g}{m}L$
