Answer:
[tex]0.12g/cm^3[/tex]
Explanation:
Firstly, you should use this formula :
[tex]Density=\frac{mass}{volume}[/tex]
We know the mass is 16.14g, and volume as [tex]138.4ml[/tex].
Also remember to convert [tex]ml[/tex] to [tex]cm^3[/tex], where [tex]1ml = 1cm^3[/tex]
Therefore, [tex]138.4ml=138.4cm^3[/tex].
Substitute the value :
[tex]\frac{16.14g}{138.4cm^3}=0.1166g/cm^3[/tex]
Rounding it to 2 significant figure :
[tex]0.12g/cm^3[/tex]
