ρ = 13534 kg / m ^ 3.
g = 9.8 m / s ^ 2.
h = 760 cm = 0.76 m.
P -?
A column of mercury 76 cm high creates a hydrostatic pressure for which the formula P = ρ * g * h is valid, where ρ is the density of mercury, g is the acceleration of gravity, h is the height of the column of mercury.
P = 13534 kg / m ^ 3 * 9.8 m / s ^ 2 * 0.76 m = 100801 Pa = 100.801 kPa.
Answer: mercury with a height of 76 cm creates a hydrostatic pressure P = 100.801 kPa.
