Use the mass and volume data to calculate the density of an unknown metal to the nearest hundredth. mass of unknown metal = 222.50 g volume of unknown metal = 25.00 what is the density of the unknown metal? 0.11 0.89 8.90 5,562.50

Density is a value for mass, such as kg, divided by a value for volume, such as m3. density is a physical property of a substance that represents the mass of that substance per unit volume. to calculate for the density of the unknown metal, we simply divide the mass of the substance by the volume measured. we do as follows:

density = mass / volume
density = 222.50 g / 25 ml
density = 8.9 g/ml

therefore, the correct answer would be the third option. the density of the unknown metal would be 8.9 grams per milliliter. it would have a high density as expected since it is a metal and it would occupy a small space but would have a heavy mass.

Neither model is able to show the reactivity of potassium.
