Because the purpose of our experiment was to verify Dalton’s law, our hypothesis was his law.

Our hypothesis for regular air looked like this: total pressure (100%) = partial pressure of oxygen (22%) + partial pressure of nitrogen (78%).

Our hypothesis for the Nitrox we used (a mixture of 40% oxygen and 60% nitrogen) was: total pressure (100%) = partial pressure of oxygen (40%) + partial pressure of nitrogen (60%).

see results graph for a comparison between our hypothesis and our results
