To save the graph as a PNG file and upload it to  Chem21labs: Click on your Excel graph and copy/paste it into WORD (use the Paste Special feature and select Picture  (PNG)).  In WORD, right click on the image and select  Save as Picture.
the Choose File button to find this image in your  computer's file structure. Upload the image by clicking the Submit button  - the  graph will display in the space below.  Note : If it does  not display, make sure you have the picture saved as a  png file and try again.  If the image is not oriented properly, use the Rotate Left and Rotate Right links.  If you need to replace the  image, use the Change Image link.   Note:  If you can't see the image or if you can't clearly  make out the essential parts of the graph (title, axes  labels, etc.), neither can your Instructor / TA.  Please try again or ask for help at a help session. Rotate Left | Rotate Right Edit Answer [Answer Correct] DISCUSSION AND ERROR ANALYSIS IMPORTANT:  These must be written independently.  It is ok to discuss the concepts in all 3 essays before you start writing ANY  of the essays. But as soon as you start wr first essay you must work independently. Copied essays will receive no credit. Paraph ALSO copying. Copied essays may also result in an ethics charge. 12.    How does this experiment relate to gases?  need to identify and define or explain the two major  concepts that relate to gases and discuss how they were  used in the experiment by relating the concepts to the  experimental procedures, observations, and results. You 
The second major concept used was the Ideal Gas Law(PV=nRT) which combines Boyle's la law, Avogrado's law, and Gay-Lussac's law, giving a relationship between a gas's pressur moles, and temperature. The Ideal Gas Law was used in order to determine the partial p air(Pair) at a given temperature from the experiment by rearranging the equation to s pressure(Pair=nairRT/V) for each respective temperature and volume of the bubble. This possible the calculation of Pwater since Pair is needed to solve for Pwater(using Dalton's results abide by the Ideal Gas Law because they demonstrate the inversely proportional r between volume and pressure in that as the pressure in the bubble decreases, the volum bubble increases and vice versa, and they also demonstrate the directly proportional re
