The Mole Project:
Part 1: -Avogadro's number is the number of atoms in one mole of an element. One mole of oxygen has a mass of 16 grams (the atomic weight).
One mole of hydrogen has a mass of 1 gram (its atomic weight).
Avogadro number says if you have one mole of something, it has 6.022*10^23 of atoms in it.
So, theres 6.022*10^23 atoms in 16 grams of oxygen, just as there is 6.022*10^23 atoms also in 1 gram of hydrogen.

1 sandwich= 1 cheese + 2 slices of bread
13 bread slices / 2 slices per sandwich = ~5 sandwiches w/ 5 cheeses worth.
5 sandwiches + cheese is the limiting reagent.
13 bread slices / 2 slices per sandwich = ~5 sandwiches w/ 5 cheeses worth.
5 sandwiches + cheese is the limiting reagent.
Number of sandwiches per ingredient:
Patties: 8
Buns: 6
Cheese: 7
Tomato: 9
Lettuce: 8
Onion: 9
Theoretical number is metion next the ingredient.
The Buns give you the lowest number theoretical yield which makes it the limiting reagent, 6.
