A metal cube has a mass of 20 g and a volume of 5 ml. What is the density? Is the cube made of pure aluminum? Explain your answer in the "other" area. * A.2.7 g/mL B.4 g/mL C.100 g/ml D. Yes it is aluminum E. No it is not aluminum Other:

The density of Aluminium is 2.7 g/mL.  The cube is not the Aluminium cube.So, option B and E is correct

Mass of metal cube, m = 20 g

Volume of cube, V =5 mL

The formula for density is as follows:-

......(1)

Substitute 20 g for mass, and 5 ml for volume in the above equation as follows:-

So, the density of the cube is 4 g/ml.

We know that the density of Aluminium is 2.7 g/mL.  So, the cube is not the Aluminium cube. So option B and E are correct.

Explanation:

Given that,

Mass of metal cube, m = 20 g

Volume of cube, V =5 mL

We need to find the density of the cube. Mass per unit volume equals density.

So, the density of the cube is 4 g/ml.

We know that the density of Aluminium is 4 g/mL.

So, the cube is not Aluminium cube.

b is the correct
