Title: Expanding the Road Map
Course: Stoichiometry

The Road Map Gets Bigger....

So far, you have seen the road map useful for mass to mass calculations:

This road map works well for several problems, but it leaves a few concepts out. We need to expand the mass - mass road map to include the following:

- Particles of a substance
- Volume of a gas at STP (Standard Temperature-Pressure)

Therefore the expanded road looks like this:

Notes to keep in mind about the full road map:

1. It is just an expansion of the mass - mass road map. It CAN be used to perform mass - mass calculations!!!

2. You do not have to start and/or end at one of the end boxes!!! You CAN start ANYWHERE on the road map and end ANYWHERE on the road map!!!

3. Since the road map is more complex, it is important now (more than ever) to label your "given" and your "unknown" to determine your starting and stopping places on the full road map.
