I don't know what category to put this question in, but I attached a photo of it. Can someone please help me answer it?

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

i'm pretty sure its b i might be wrong though!
