Question

Density,mass of metals of equal volumes of iron and aluminium have __________________masses.

Answer 1

1. Density is mass per unit volume of a substance.
2. Equal volumes of iron and aluminium have different masses because they have different densities.
3. Iron has greater mass than aluminium and gravitational force acting on the iron will be higher compared to that of aluminium.

Hence, the density, mass of metals of equal volumes of iron and aluminium have different (unequal) masses.
