Question

1. 2KCIO3, -- 2KCI + 302
How many moles of O2 will be produced from 2.25 moles of KCIO3?

Answer 1

Answer:

3.375moles of O₂

Explanation:

The reaction expression is given as;

                   2KClO₃ → 2KCl + 3O₂

Number of moles of KClO₃  = 2.25moles

Now;

To find the number of moles of O₂ produced we use known number of moles.

So;

                  2 mole of KClO₃ will produce 3 moles of O₂

                 2.25moles of KClO₃ will produce $\frac{2.25 x 3}{2}$   = 3.375moles of O₂
