The table shows the mass and density of some substances. part 1: is the value of q less than, greater than, or equal to the value of p? part 2: explain your answer for part 1. density of substances mass (g) density of iron (g/cm3) density of silver (g/cm3) 100 7.8 q 200 p 19.3

(1) and (2) Density is an intrinsic property of the substance and is calculated by dividing the given mass by the volume. That is shown in the equation,
          D = mass / volume

This means that at a certain temperature and environmental condition, the value is unique to the substance. The value of Q, which is the density of silver when mass is 100 g is supposed to be greater than the value of P, which is the density of iron when mass is 200 g.
