    You can use the formula



    where = pressure, = density of mercury, = acceleration due to gravity, and = the height of the mercury column. The quantity is equal to the weight density of the fluid (W), so depending on the data that your text book provides you may want to use .

    Do you know the denisty of mercury? Plug it into the equation I gave you in the previous post - what do you get? If you're having difficulty show us what you've attempted to solve this and we'll help you along, but we won't give homework answers for you.
