an unknown metal has a volume of 20cm^3 and a mass of 54g. Identify the metal
To identify the metal, we can make use of its density. Density is a physical property unique to each material, and it can be calculated by dividing the mass of an object by its volume.
The formula for density is:
Density = Mass / Volume
In this case, the mass is given as 54g, and the volume is given as 20 cm^3. Let's substitute these values into the formula:
Density = 54g / 20 cm^3 = 2.7 g/cm^3
Now, we can compare this density value with the densities of known metals to identify the unknown metal. You can either refer to a table of densities or use an online resource to find the density of various metals.
Based on the density value obtained, it appears that the unknown metal has a density of 2.7 g/cm^3. By comparing this value to the densities of known metals, you can determine the identity of the metal.
