A salt is formed between a bivalent metal cation and an oxyacid of a non-metal. The-ous acid of the non-metal has twooxygen atoms per molecule. If thesalt contains a radicalof per acidof the same non-metal, calculate the number of atoms of variouselements present in 0.5 moles of thesalt.

1.	A salt is formed between a bivalent metal cation and an oxyacid of a non-metal. The-ous acid of the non-metal has twooxygen atoms per molecule. If thesalt contains a radicalof per acidof the same non-metal, calculate the number of atoms of variouselements present in 0.5 moles of thesalt.
Answer» Solution :(i) identification of acidic redical and formula of salt (ii) determination of theformula ofthe 'per' acidradical (III) determination of the formula ofthesalt (IV) determination of thenumber of atoms of each CONSTITUENT ELEMENT, present in one molecule of thesalt (v) determination of thenumber of atoms of each constituent element, present in 5 moles of the salt (vi)4 N oxygen atoms N chlorine atoms
