    2ft X 12in/ft X 25.4 mm/in less than the previous question.

    Essentially the same question was asked yesterday. We don't just give answers to your questions but I gave an outline of how to do it. Use that hint with the one I gave you today and you should be able to do it. Let us know if you need more help.

    You can find the pressure that this new height exerts.

    Pressure = Force/Area = (Mass x Gravity) / Area = ((Density/Volume) x Gravity)/Area = (Density x Gravity) / (Volume x Area) = (Density x Gravity) / (Height)

    Then convert this extra pressure into mm Hg.

    Now, I can't find the previous question... and it wasn't deleted...
