1. Decide what is being asked(starting unit and ending unit)

2. Write down all the given information

3. Use the starting unit to follow to mole roadmap(pictured below) to convert into the ending unit

4. Round to the correct number of significant figures. This will be the least amount of sig figs in any of the present values in the conversions.
