How many moles of O2 gas will be produced at STP from 4 moles of KC1O3

6moles of O2 will be produced

Explanation:

Step 1: write the correct and balance the equation

2KClO3 > 2KCl + 3O2

Step 2: find the mole

2 moles of KClO3 gives 3moles of O2

We are provided with 4 moles of KClO3,

Since 2 moles of KClO3 = 3 moles of O2

4 moles of KClO3 = x moles of O2

Cross multiply

2 = 3

4 = x

4 * 3 = 2 * x

12 = 2x

Divide both sides by 2 , to get the mole of O2

12/2 = 2x/ 2

6 = x

x = 6

The mole of O2 is 6 moles
