Answer:

Approx. #230*g#....

Explanation:

By definition, #"density,"# #rho="mass"/"volume"#...

..and thus to get the #"mass"# we take the product....

#"mass"=rhoxx"volume"#...and here are quoted both #rho# and #"volume"#. And so.....

#"mass"=underbrace(13.6*g*cancel(cm^-3))_"density"xxunderbrace(16.8*cancel(cm^3))_"volume"=underbrace(??*g)_"mass"#.

Often, in the lab you can pick up a container of mercury, and be surprised by its mass....mercury is dense stuff....
