How to solve numericals based on the mole concept?
There are mainly 4 types of problems in mole concept.
- Type 1: To find no. of moles in a given mass no. of moles=given mass/atomic or molecular mass.
- Type 2: To find no. of atoms/molecules in a given mass : first the no. of moles by using the formula that we've used to solve Type 1 numericals and multiply the answer with Avagadro constant.
- Type 3: To find no. atoms/molecules in a given mole :No.of atoms/molecules in a given no. of mole=No. of mole * Avogadro no.
- Type 4: To find mass of an atom(s)/molecule(s) :Mass of atoms or molecules=Gram atomic or molecular mass/Avogadro number.
