Explanation / Answer

P = hdg

P = pressure

h = height of the column = 661 mm

d = densuty of n-butyl phthalate = 1.046 g/ml

g = gravity = 9.8 m/s^2

so taht,

h1d1g = h2d2g

h1d1 = h2d2

h1 = height of the n-butyl phthalate column = 661 mm

d1 = 1.046 g/ml

h2 = height of the mercury column = ?

d2 = density of mercury = 13.53 g/ml

(661*1.046) = (h2*13.53)

h2 = 51.1 mm hg

1 mm hg = 1 torr

h2 = 51.1 torr
