The density of the iron pyrite cube is 1.343 g/cm³.
Given,
Side of iron pyrite cube = 0.31 cm
Mass of iron pyrite = 0.040 g
The volume of iron pyrite cube = s³ cm³
Or, volume = 0.029791 cm³
We have to find the density of the sample.
Density is defined as the mass per unit volume. Or, it is the ratio of mass to the volume of the substance.
Using the formula for density, we get,
Density = mass/volume
Or, density = 0.40/0.029791
Or, density = 1.343 g/cm³
Hence, the density of the iron pyrite cube is 1.343 g/cm³.
