Calcium oxide - Wikipedia

Calcium oxide (CaO), 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 materials, in which carbonates, oxides and hydroxides of calcium , silicon, magnesium, aluminium, and iron predominate.

Calcium oxide - Wikipedia

The Relative Molecular Mass of a compound is the sum of the masses of all the atoms present in the molecule. It is often shortened to RMM. The RMM is used in many sorts of calculations in chemistry, and so you must be able to calculate it to answer all the other calculations you might meet.
