Quizplus · Accepted Answer

To determine the density of the unknown metal, we need to divide its mass (0.095 g) by its volume (0.250 cm x 0.250 cm x 0.250 cm = 0.0156 cm^3). This gives us a density of approximately 6.09 g/cm^3. Comparing this density to the densities of the metals listed, we can see that vanadium has the closest density at 6.11 g/cm^3. Therefore, the most likely unknown metal is vanadium.
