Molar mass of calcium oxide

Calcium oxide formula : Ca O , commonly known as quicklime or burnt lime , is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature. The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium , aluminium , and iron predominate. By contrast, quicklime specifically applies to the single compound calcium oxide. Calcium oxide that survives processing without reacting in building products , such as cement , is called free lime. Quicklime is relatively inexpensive. Both it and the chemical derivative calcium hydroxide of which quicklime is the base anhydride are important commodity chemicals. Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells , that contain calcium carbonate CaCO 3 ; mineral calcite in a lime kiln. This is also one of the few chemical reactions known in prehistoric times. The quicklime is not stable and, when cooled, will spontaneously react with CO 2 from the air until, after enough time, it will be completely converted back to calcium carbonate unless slaked with water to set as lime plaster or lime mortar. Annual worldwide production of quicklime is around million tonnes. China is by far the world's largest producer, with a total of around million tonnes per year. The United States is the next largest, with around 20 million tonnes per year.

These names refer to the traditional method of producing calcium oxide by heating calcium carbonate such as limestone to a high temperature, resulting in the decomposition of the carbonate and the formation of calcium oxide.

Molar mass of calcium oxide

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight in atomic mass units of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom or group of atoms in the formula by the formula weight and multiplying by A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert.
