Answer:
[tex]\rho =0.9g/mL[/tex]
Explanation:
Hello,
In this case, due to the volume displacement caused the by the object's submersion, it's volume is:
[tex]V=11.8mL-4.5mL=7.3 mL[/tex]
In such a way, considering the mathematical definition of density, it turns out:
[tex]\rho =\frac{m}{V}=\frac{6.5g}{7.3mL}\\ \\\rho =0.89g/mL[/tex]
Rounding to the nearest tenth we finally obtain:
[tex]\rho =0.9g/mL[/tex]
Regards.
