Calculating the Mass of KCl Produced from One Mole of KClO3:

To calculate the mass of KCl produced from one mole of KClO3, we need to follow these steps:

1. Write the balanced chemical equation for the reaction between KClO3 and KCl:

2 KClO3 → 2 KCl + 3 O2

2. Calculate the molar mass of KClO3 and KCl:

- Molar mass of KClO3 = 122.55 g/mol
- Molar mass of KCl = 74.55 g/mol

3. Determine the theoretical yield of KCl:

- One mole of KClO3 produces two moles of KCl
- Therefore, the theoretical yield of KCl is 2 x 74.55 g/mol = 149.10 g/mol

4. Calculate the actual yield of KCl:

- The percentage yield is given as 80%
- Therefore, the actual yield of KCl is 80% of the theoretical yield
- Actual yield of KCl = 0.8 x 149.10 g/mol = 119.28 g/mol

5. Determine the mass of KCl produced from one mole of KClO3:

- The mass of KCl produced from one mole of KClO3 is equal to the actual yield of KCl
- Therefore, the mass of KCl produced from one mole of KClO3 is 119.28 g/mol

Explanation:

The balanced chemical equation shows that two moles of KCl are produced from one mole of KClO3. The molar mass of KClO3 and KCl are used to calculate the theoretical yield of KCl, which is the maximum amount of KCl that can be produced from one mole of KClO3. However, the actual yield of KCl is given as 80% of the theoretical yield, which means that some KClO3 did not react to form KCl. Finally, the mass of KCl produced from one mole of KClO3 is equal to the actual yield of KCl.
