Jack's rock has a density of #7*g*cm^-3#.

Explanation:

#"Density, "rho="Mass"/"Volume"#.

And thus with the given units, we simply set up this quotient:

#"Mass"/"Volume"=(14*g)/(2*cm^3)#, and #rho=??#; and you can see that this quotient gives the required units of #g*cm^-3-=g*mL^-1#. Capisce?

I suggest Jack does not advertize his possession.
