Question

If 20.00 moles of KClO3 react, how many molecules of O2 will form?

Answer 1

Step-by-step explanation:

2KClO₃ = 2KCl + 3O₂

2 moles of potassium chlorate gives 3 moles of oxygen gas

20 moles of potassium chlorate will give 30 moles of oxygen gas .

30 moles of oxygen = 30 x 6.02 x 10²³ molecules of oxygen .

= 180.6 x 10²³ molecules of O₂ .
