For example, in the amphibole mineral tremolite - Ca 2 Mg 5 Si 8 O 22 (OH) 2, if Al +3 replaces one of the Si +4 ions then Na +1 can go into a site that is normally vacant to maintain charge balance. The resulting formula would be NaCa 2 Mg 5 AlSi 7 O 22 (OH) 2 .

Specific gravity is the ratio between the mass (weight) of a mineral and the mass (weight) of an equal volume of water. A mineral's specific gravity (SG) can be determined by dividing its weight in air by the weight of an equal volume of water. For instance, quartz with a density of 2.65 is 2.65 times as heavy as the same volume of water.
