Stoichiometry Lesson #1

I have 5 eggs, how many cookies can I make? (assume there is enough of every other ingredient)

In a balanced chemical equation, coefficients represent ___.

2KClO₃ --> 2KCl + 3O₂

How many moles of oxygen (O₂) can be produced from the decomposition of 15.0 moles of potassium chlorate (KClO₃)?

2H₂O --> 2H₂ + O₂

How many grams of hydrogen (H₂) could be produced from the decomposition of 25.0 moles of water (H₂O)?

4NH₃ + 5O₂ --> 4NO + 6H₂O

How many moles of NH₃ are required to produce 40.0 grams of NO?

The FIRST step in this problem is to...

2 KClO₃ → 2 KCl + 3 O₂

How many moles of oxygen are produced when 6.7 moles of KClO₃ decompose completely?

Using the following equation:

Fe₂O₃(s) + 3H₂(g) → 2Fe(s) + 3H₂O(l)

How many moles of iron (Fe) can be made from 6 moles H₂?

What is the mole ratio in the following reaction:

2CO + O₂ → 2CO₂

How many particles are in a mole?

How many moles are in 19.82 g Mg?
