a cube of an unknown metal has a volume of 2.25 cm³ and a mass of 16.2 g. based on data in the table above, what is the identity of this metal? polonium ruthenium chromium bismuth

Answer

Explanation:

Step1: Calcular la densidad

La densidad ($\rho$) se calcula con la fórmula $\rho=\frac{m}{V}$, donde $m$ es la masa y $V$ es el volumen. Dados $m = 16.2\ g$ y $V=2.25\ cm^{3}$, entonces $\rho=\frac{16.2}{2.25}$

Step2: Obtener el valor de la densidad

$\rho = 7.2\ g/cm^{3}$

Step3: Comparar con los valores de la tabla

Buscar en la tabla el metal con una densidad cercana a $7.2\ g/cm^{3}$.

Answer:

Chromium
