density of mercury =13.60 g cm-3

density of oil = 1.045 g cm -3

acceleration due to gravity = 9.806 m s-2

(a) What is the pressure of the gas?

(b) What is the difference in height of the oil in the two arms of the oil pressure gauge?

2. Pressure = density * g * h

3. for part a, do i find the pressure of the gas by using P=pgh and just plugging in the density of mercury, the height difference, and the gravitational constant?

and can i just use that answer to find the difference in height of the oil by using P=pgh with P=the pressure from a, g, and p=the density of oil?
