12.7: Moles- Counting Atoms

Is there an easier way to load this truck?

When the weather is nice, many people begin to work on their yards and homes. For many projects, sand is needed as a foundation for a walk or to add to other materials. You could order up twenty million grains of sand and have people really stare at you. You could order by the pound, but that takes a lot of time weighing out. The best bet is to order by the yard, meaning a cubic yard. The loader can easily scoop up what you need and put it directly in your truck.

It turns out there are also convenient ways of counting how much we have in chemistry. We will introduce some of those in this chapter. The first section will relate to counting atoms, and the second section will relate counting atoms to mass.
