Document Summary

Keep in mind that there will often be multiple ways of approaching a given question; at times, my approach will differ from what you may have done or from how it is done in the book. Understanding how different approaches all fundamentally mean the same thing will go much further towards improving your understanding than memorizing one best way. understanding that will come out and bite you later. If your approach is very different, this may be brilliant or it may signal a aw in: a) recalling that 1 atm is equal to the pressure of 760 mm hg: 0. 984 atm x 760 mmhg/atm= 748 mm hg: torr is just another way of writing mm hg, really. So 928 mm hg: this is a comparison of densities. Draw it out to help you visualize it. Both levels are above the reference point, so it s really a coy way of stating the difference between them.
