Matter and Measurements 1

In class today, we learned about dimensional analysis, or the conversion of one quantity to another. With this knowledge, we can calculate problems such as the number of seconds in a given amount of days. We also learned about density and temperature and how to calculate each one. The diagram below shows how to calculate density:





The diagram shows that mass is equal to density times volume, volume is equal to mass divided by density, and density is equal to mass divided by volume. I find this diagram useful because it not only simplifies the density formula we learned in class, but it also provides a refresher of how to calculate mass and volume as well. In the future, I predict that dimensional analysis will be an essential part of most chemistry units in the future.
