A:

As described in the previous question the density is given by D = M/V. If you don't know V then you have to compare the density of the unknown to that of a known density, e.g. water.

Call the density of the object Do and the density of water Dwater. The weight of the object in air is then Mair = Do * V. The weight of the object in water is Mwater = (Do - Dwater) * V.

Dividing one equation by the other the volume V cancels out and the ratio of the two measurements is Mair/Mwater = Do/(Do - Dwater). Using the value of Dwater as 1 gram per cubic centimeter you can easily solve this equation for the density of the object Do.
