Answer:

[tex]\rho = 2.7g/mL[/tex]

Explanation:

Hello,

In this case, given that the density for a material es defined via its mass and volume:

[tex]\rho =\frac{m}{V}[/tex]

We first need to compute the volume of aluminum in this case, since it comes from the volume of cylinder and the volume of the cylinder with the aluminum:

[tex]V=15.46 mL-10.00mL\\\\V=5.46mL[/tex]

In such a way, the density turns out:

[tex]\rho=\frac{14.74g}{5.46mL}\\ \\\rho = 2.7g/mL[/tex]

Best regards.
