Question

Give the relationship between mole, mass and Avogadro number.

Answer 1

1. One mole of a substance has $\left(6.022\mathrm{x}{10}^{23}\right)$ particles of that substance, with mass equal to its atomic or molecular mass in grams.
2. The quantity $\left(6.022\mathrm{x}{10}^{23}\right)$ is referred to as the Avogadro's Number
3. In the form of an equation, this relationship can be represented as,
   1. Number of moles = (Given mass)/(Molar mass)
   2. Number of moles = (Given number of particles)/(Avogadro's number)
