If the pressure is 748 mmHg, and if h= 35mm, what is the pressure of the gas, expressed in atm, If the substance in the tube is oil having a density of 0.788 g/mL? The density of mercury is 13.6 g/mL.

Answer 1

I don't think your post is clear. I don't know what you're asking. It appears to me that if the pressure is 748 mm Hg then the pressure is 748/760 = ? atm and I know that isn't what you're asking.
