How many atoms and ions does lithium sulfite have?

Hence the ions per mole are:

In one mole of Li2SO3 , the number of the atoms are

Explanation:

The formula of  lithium sulfite is Li2SO3.

It contain Li+ and SO3(2-) ions.This can be represented by :

Hence one mole of Li2SO3 will give 2 Li+ ions and 1 SO3 (2-) ion.

Hence the ions per mole are:

Number of atoms in  lithium sulfite depends upon the mass of the Li2SO3 present .

Li2SO3 = 93.94 g/mole

This mass is equal to 1 mole of Li2SO3

Now 1 mole of any substance contain Na atoms . This is known as Avogadro Number.

Hence , if 1 mole of Li2SO3 is present then it contains Na atoms

If other then 1 mole present then number of atoms are calculated by:

Here n = number of moles

if the mass of the compound is given then first calculate the number of moles.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
