Galena specific gravity.

Specific Gravity = massoftheobject massofthewater = mobject mH2O. Moreover, the mass of the object is also directly related to the density. In addition, the mass is measured in Newtons. Furthermore, we can also find specific gravity with the weight of the object and water. Specific Gravity = weightoftheobject weightofthewater = Wobject WH2O. Chemistry questions and answers. - 1.
