Analysing the question:
To calculate the density of a material, we need its mass and volume
We are given:
Mass of sample = 21 grams
dimensions of the sample = 1 * 1 * 2 = 2 cm³
Calculating the density:
Density = Mass of sample / volume of sample
Replacing the variables
Density = 21 / 2
Density = 10.5 g / cm³
Determining the Material:
From the table provided, we can see that the density of Silver is 10.5 g/cm³
Therefore, the material is Silver
