`O_(2)` is evolved by heating `KClO_(3)` using `MnO_(2)` as a catalyst
`2KClO_(3) overset(MnO_(2))to 2KCl+3O_(2)`
Calculate the number of moles of oxygen produced in the above reaction if 56g of `KClO_(3)` is used.

Explanation

To solve the problem, we need to calculate the number of moles of oxygen produced when 56 g of KClO₃ is heated. We will follow these steps:

### Step 1: Calculate the molar mass of KClO₃
The molar mass of KClO₃ can be calculated by adding the atomic masses of its constituent elements:
- Potassium (K): 39 g/mol
- Chlorine (Cl): 35.5 g/mol
- Oxygen (O): 16 g/mol (and there are 3 oxygen atoms in KClO₃)
