In an experiment, a mixture of two gases occupies a volume of 3.00 L at a temperature of 22.5 degree centigrade. The mixture contains 14.0 g of water, 11.5 g of oxygen, and 37.3 g of nitrogen. Calculate the total pressure and the partial pressure of each gas?

  1. 1. This is a homework help site, not a homework do site; i.e., our objective on this site is to help students understand a concept so they may work through a problem. That is to say that we USUALLY do NOT provide direct answers.

    2. Most of us volunteers want to see what the student thinks before we give an answer. In fact, we prefer the student tell us what s/he thinks and that could be done with the original post. In your case it was not.

    3. When the student fails to do that, we are left with no recourse except to ask, "What do you think?" as a way of getting the student involved in thinking about the question. In no way does that imply rudeness nor impropriety. In fact we could think the student as rude for being an answer moocher but I think most of us have thicker skins than that.

    4. We recognize that some students need more help than others and help is what we give (with the emphasis on help and not on do). So help us help you by being as upfront from the beginning and tell us what you already know about the question and/or what you don't understand about it. The more we know the more we can help.

  2. Do we assume the H2O is liquid and it occupies no volume. Convert grams of each gas to mols (mols = grams/molar mass) and use PV = nRT to calculate pressure of each gas. Sum of the partial pressures will give Ptotal.
