question 27 of 30 > an unknown metal has a mass of 25.2 g and a volume of 3.5 cm³. the density of some metals is shown in the table. metal density aluminum 2.7 g/cm³ zinc 7.1 g/cm³ copper 9.0 g/cm³ lead 11.4 g/cm³ which metal is most likely to be the identity of the unknown metal? lead aluminum zinc copper

Answer

Explanation:

Step1: Recall density formula

The formula for density is $\rho=\frac{m}{V}$, where $\rho$ is density, $m$ is mass and $V$ is volume.

Step2: Substitute given values

Given $m = 25.2$ g and $V=3.5$ cm³, then $\rho=\frac{25.2}{3.5}=7.2$ g/cm³.

Step3: Compare with known densities

The calculated density of $7.2$ g/cm³ is closest to the density of zinc ($7.1$ g/cm³) in the table.

Answer:

zinc
