Apiece of an unknown metal has a volume of 19.8 ml and a mass of 210.0 grams. the density of the metal is g/ml a piece of the same metal with a mass of 86.0 grams would have a volume of ml.

The density of the metal is 10.60 g/mL and the volume occupied by 86.0 grams is 8.11 mL

Explanation:

To calculate the density of unknown metal, we use the equation:

      ......(1)

Volume of unknown metal = 19.8 mL

Mass of unknown metal = 210.0 g

Putting values in equation 1, we get:

The density of the metal remains the same.

Now, calculating the volume of unknown metal, using equation 1, we get:

Density of unknown metal = 11.45 /mL

Mass of unknown metal = 86.0 g

Putting values in above equation, we get:

Hence, the density of the metal is 10.60 g/mL and the volume occupied by 86.0 grams is 8.11 mL

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck
