- 1 hamburger bun
- 2 hamburger patties
- 2 slices of cheese
- 4 strips of bacon

- If I have five bacon double cheeseburgers:
- How many hamburger buns do I have?
- How many hamburger patties do I have?
- How many slices of cheese do I have?
- How many strips of bacon do I have?

- How many bacon double cheeseburgers can you make if you start with:
- 1 bun, 2 patties, 2 slices of cheese, 4 strips of bacon
- 2 bun, 4 patties, 4 slices of cheese, 8 strips of bacon
- 1 dozen bun, 2 dozen patties, 2 dozen slices of cheese, 4 dozen strips of bacon
- 1 mole bun, 2 mole patties, 2 mole slices of cheese, 4 mole strips of bacon
- 10 bun, 20 patties, 2 slices of cheese, 40 strips of bacon

- If you had fixings for 100 bacon double cheeseburgers, but when you were cooking you ruined 10 of them. What percentage of the bacon double cheeseburgers do you actually make?

- Na
^{+}+ Cl^{-}-> NaCl - 1 mole of H
_{2}SO_{4}+ 2 mole NaOH produce 1 mole Na_{2}SO_{4}+ 2 mole H_{2}O

- If I have 1 mole of NaCl
- How many moles of sodium do I have?
- How many moles of Chloride do I have?

- If I want to make 5 moles of Na
_{2}SO_{4}:- How many moles of H
_{2}SO_{4}do I need? - How many moles of NaOH do I need?

- How many moles of H
- How much Na
_{2}SO_{4}can I make if I have:- 1 mole of H
_{2}SO_{4}and 2 mole of NaOH - 10 mole of H
_{2}SO_{4}and 20 mole of NaOH - 0.1 mole of H
_{2}SO_{4}and 0.2 mole of NaOH - 1 mole of H
_{2}SO_{4}and 20 mole of NaOH - 0.42 mole of H
_{2}SO_{4}and 0.65 mole of NaOH - 5 grams of H
_{2}SO_{4}and 5 grams of NaOH
