Solving applied mass percent problems Cobalt(II) chloride forms several hydrates with the general formula CoCl, xH,0, where x is an integer. If the hydrate is heated, the water can be driven off, leaving pure CoCl, behind. Suppose a sample of a certaln hydrate is heated until all the water is removed, and it's found that the mass of the sample decreases by 45.%. Whích hydrate is It? That is, what is x?

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
