Question

Please help me with all the Formulas that will be used in Mole Concept that we also used in class 9 but not to a great extent. Please help me with all of the formulas of Mole Concept! ASAP😇😇

Answer 1

The following formulas are used in the calculations :

○ Number of moles (n) = Given number of particles (N) / Avogadro number (N0)

○ Number of atoms (n) = Given mass (m) / (Molar mass (M) x Avogadro number (N0) )

○ Number of molecules (n) = Given mass (m) / (Molar mass (M) x Avogadro number (N0) )

○ Number of particles (n) = Number of moles of particles (n) x Avogadro number (N0)

Note: We can also use formula

$No.ofmoles=\frac{Givenmass}{Molecularmass}=\frac{No.ofparticles\left(or\right)No.ofatoms\left(or\right)No.ofmolecules}{Avagadronumber}$

These formulas will help you to do problems in mole concept.
