A block of iron is suspended from one end of an equal-arm balance by a thin wire. To balance the scales, 4.45 kg are needed on the scale pan at the other end. The density of iron is 7.87×10^3 kg/m^3 and the density of water is 9.98×10^2 kg/m^3. What is the volume of the block (in m^3)? Next, a beaker of water is placed so that the iron block, suspended as above, is submerged in the beaker but not touching the bottom. What mass (in kg) is now necessary to balance the scales?

Density of Solids

The density of a substance refers to how much matter is present in a given amount of space. It is expressed as the ratio of the mass of the substance to its volume.
