There are many minerals which contain silver. A 2.22 g sample of one of these, matildite, is placed in water and all of its silver ions are released. It takes 1.91 mL of 1.53 M magnesium chloride to precipitate all the silver lons just released as the solid silver chloride. Calculate the mass percent of silver in matildite to the correct number of significant figures. Assume that matildite contains no chloride ions.

Crystal Structures

Solids are present all around us. They have different properties and applications. Diamond and graphite are two well-known solids. Diamond is the hardest material in the world and is used in making jewelry. Graphite on the other hand is soft. The lead of your pencil is graphite. Why are they so different in appearance and properties despite the fact they are chemically the same? Both are allotropes of carbon. The answer lies in the structure, the way constituent particles are arranged in the solids.
