Molecular 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.

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. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. We use the most common isotopes. This is how to calculate molar mass average molecular weight , which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.

Magnesium hydroxide is a substitute for lime in pH control, and magnesium oxide is a substitute for dolomitic lime as a flux in steelmaking. Limestone, which contains less reactive material, is slower to react and may have other disadvantages compared with lime, depending on the application; however, limestone is considerably less expensive than lime.

The formula CaO represents calcium oxide, showcasing the elemental composition of one calcium atom bonded to one oxygen atom. Chemical formula. China is by far the world's largest producer, with a total of around million tonnes per year. Add them together: add the results from step 3 to get the total molar mass of the compound. Since there is one calcium atom and one oxygen atom in calcium oxide, we can add their atomic masses together:. Limestone, which contains less reactive material, is slower to react and may have other disadvantages compared with lime, depending on the application; however, limestone is considerably less expensive than lime.
