Question

A cup of gold colored metal bed was measured to have a mask for 25 g. By water displacement, the volume of the bed was calculated to be 40.0 mL. Given the following densities, identify the metal. Gold equals 19.3 g/milliliters copper equals 8.86 g/milliliters bronze equals 9.87 g/milliliters

Answer 1

Answer : The metal is copper.

Explanation :

As we are given that:

Mass of metal = 25 g

Volume of metal = 40.0 mL

Formula used:

$\text{Density of metal}=\frac{\text{Mass of metal}}{\text{Volume of metal}}$

Now putting all the given values in this formula, we get:

$\text{Density of metal}=\frac{25g}{40.0mL}$

$\text{Density of metal}=8.86g/mL$

From this we conclude that the metal is copper whose density is 8.86 g/mL.

Hence, the metal is copper.
