Question

A general chemistry student found a chunk of metal in the basement of a friend's house. To figure out what it was, he used the ideas just developed in class about density.First he measured the mass of the metal to be 145.6 grams. Then he dropped the metal into a measuring cup and found that it displaced 19.9 mL of water.Calculate the density of the metal.

Answer 1

Since the density of the metal is 7.3g/ml, the metal is likely to be Chromium.

Step-by-step explanation:

The given information about the metal is:

- Mass (m): 145.6g

- Volume (v): 19.9mL

To calculate the density of the metal, we have to replace the values of mass and volume in the density formula:

`\begin{gathered} Density=(Mass)/(Volume) \\ Density=(145.6g)/(19.9mL) \\ Density=7.3(g)/(mL) \end{gathered}`

So, since the density of the metal is 7.3g/ml, the metal is likely to be Chromium.
