Okay, so this site is awesome and will come in handy..

Maybe someone can give me a hand with the following question:

Mercury has a density of 13.96 g/cm3. A barometer is constructed using an oil with a density of 0.75g/cm3. If the atmospheric pressure is 1.0 atm, what will be the height in meters of the oil column in the barometer?

As I have been reviewing for a test I came across this question. The textbook lists the answer as 14m. Though that does not help because I have not a clue as how you'd arrive to that answer. Can someone lend me some much needed guidance?

Thanks!

You may start from pressure definition - calculate what is pressure exerted on the surface by the cylinder of base surface S, height h and density d.
