Question

What is the symbol for SI unit of mole and how is it defined?

Answer 1

Mole concept:

• It is a way of measuring the amount of substance.
• When the atomic or molecular level is concerned, it becomes difficult for us understand to calculate as at quantum levels the particles are extremely small and huge in numbers.
• So to deal with this situation we use mole, which is a count of a very large number of particles.
• $1\mathrm{mole}=6.022\times {10}^{23}$
• This number is also known as the Avogadro number and is denoted by $\left({\mathrm{N}}_{\mathrm{A}}\right)$,
• SI unit symbol is “mol”.
