Dimensional Analysis |
using conversion units to solve chemistry problems (factor-label method) |
|
|
What is dimensional analysis based on? |
different units that express the same quantity (e.g. 2.54cm = 1in) |
|
|
What is the general equation used for dimensional analysis? |
Given quantity x conversion factor = desired quantity |
|
|
How do the units cancel in dimensional analysis? |
given units should cancel, leaving only the desired unit |
|
|
What are the suggested steps for correctly solving chemistry problems? |
1) read the question carefully & make sketches 2) find the correct equation & conversion factors 3) check for the correct signs, units and sig figs 4) make sure the answer is reasonable 5) double check the final answer by making an estimate |
