Introduction to Stoichiometry

Mole ratios are obtained from the

Fe₂O₃(s) + 3H₂(g) → 2Fe(s) + 3H₂O(l). How many moles of iron can be made from 6 moles H₂?

12.00 moles of NaClO₃ will produce how many grams of O₂?

2 KClO₃ → 2 KCl + 3 O₂
How many moles of oxygen are produced when 6.7 moles of KClO₃ decompose completely?

Cl₂ + 2KBr → Br₂ + 2KCl How many grams of potassium chloride (KCl) can be produced from 356 g of potassium bromide (KBr)?

CH₄ + 2 O₂ → CO₂ + 2 H₂O How many moles of carbon dioxide are produced from the combustion of 110 g of CH₄?

How many grams of aluminum sulfate would be formed if 250g H₂SO₄ completely reacted with aluminum?

6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
What is the total number of moles of water needed to make 2.5 moles of C₆H₁₂O₆?

What mass of O₂ will be needed to burn 36.1 g of B₂H₆?

2Na + 2H₂O → 2NaOH+ H₂ How many grams of hydrogen are produced if 120 g of Na are available?
