More ### Quantifying the Composition of Limestone

2018-8-14  Limestone is composed of the mineral calcite, better known to chemists as calcium carbonate, small amounts of clay, silt, chert (silica, SiO2), and dolomite (calcium-magnesium carbonate, CaMg[CO3]2).2 To be called limestone, the rock has to have a composition of over 50% dolomite and calcite, though the exact percentages vary widely. The limestone available commercially is over 80% calcite and dolomite. Traditionally, the chalk in chalkboard was produced from limestone. However, the chalk used on chalkboards today is being replaced by gypsum (calcium sulfate, CaSO4). Limestone

Calculate the percentage yield for the process. (Ar values: C = 12, O = 16, Ca = 40) I worked out Ar values to be 100 for calcium carbonate and 56 for calcium oxide. Now, the way I thought to work it out is amount of product produced divided by maximum amount of product possible x 100, so: 804 / 1500 x100 but apparently this answer is incorrect.
