Answer:The purple color is due to a mixture of the pink aqua complex and blue chloro complex and is not due to a new species.
Explanation:
The pink aqua complex of cobalt can be in equilibrium with blue chloro complex of cobalt giving rise to a purple colour. This equilibrium is governed by Le Chaterliers principle. A change in chloride or water concentration could shift the equilibrium towards any of the species causing its colour to become the dominant colour of the solution.
It is a element.
Pure substances includes either compunds, or elements. Elements are the simplest form of pure substance, they only consist of one kind of atoms. On the other hand, compounds contains two or more elements that are chemically combined together. Although you couldn't separate a compound by physical methods like filtration, but you can seperate them with chemical methods such as heating or electrolysis, using electricity.
Therefore, since compounds can be broken down eventually, so, the answer will be element.
Number of moles = number of atoms/Avogadro's number
= (4.8x10^25)/(6.02x10^23)
=79.7 mol (3sf)
