If the atmospheric pressure is 0.975 atm

[priscilla89]

Homework Statement

If the atmospheric pressure is 0.975 atm, what is the pressure of the enclosed gas when its an open-tube manometer and the h is 52 cm?

The Attempt at a Solution

I know you would have to set up a proportion. I was thinking

.975 / 1 = x / 760

x = 741 torr

But you will need the density of this gas, right?

But you will need the density of this gas, right? I know we'll have to use the height but I don't know how.

This question is at this website below, its on pg 399 Q 15 i. I will appreciate the help for just one question at least.
