"xCO3" typically refers to a general formula for a chemical compound where "x" represents the molar amount of a cation (a positively charged ion) attached to a carbonate ion (CO3^2-). The specific compound will depend on the cation involved. For example, CaCO3 represents calcium carbonate, a common mineral found in rocks.
