| Dimensional Analysis |
| | Dimensional Analysis (Factor-Label Method)
|
| | From the site: "Dimensional Analysis (also called Factor-Label Method or the Unit Factor Method) is a problem-solving method that uses the fact that any number or expression can be multiplied by one without changing its value. It is a useful technique. The only danger is that you may end up thinking that chemistry is simply a math problem - which it definitely is not." |
