Moles of Gas
Definition
A mole is a unit used in chemistry that represents 6.022 x 10^23 particles (atoms or molecules) - this is known as Avogadro's Number.
Analogy
Imagine you're baking cookies for your entire school. One recipe makes about 24 cookies - let's call this "one batch." If you need to make enough cookies for everyone in your school, you'd calculate how many "batches" you need to bake. In chemistry, instead of batches we use moles to count atoms or molecules.
