Do the following conversions using the unit factor process. Show your work for each step and cancel out units as you work. The point of this lesson is not just getting the right result, which you could find on the Internet anyway. The point is to learn how to set up and carry out unit conversion. This is a useful skill and will be used throughout your chemistry course.
Do all work on a separate piece of paper and number each problem clearly.
It often happens that in doing different conversions, we use the same long sequence of conversion factors. There is a way to simplify and speed up the process of completing a conversion. To do so, we simply convert one unit into many smaller units to create a new conversion factor. Create the following conversion factors by combining conversions from the table.
Now, use those custom conversions to do things in just one step!
