Jan 28, 2017

#### Answer:

Mole is one of the main concept of chemistry. It is very useful in calculating mass of products from mass of reactants

#### Explanation:

Avogadro's constant is $6.023 \cdot {10}^{23}$. This represents the number of atoms in 12 grams of carbon. A mole has $6.022 \cdot {10}^{23} \text{molecules}$.

For example, if a limited amount of compound or element $x$ has $12.044 \cdot {10}^{23}$ molecules. The amount of element $x$ is said to be $2$ moles of $x$.
