Initial data: h (height of the mercury column) = 76 cm.

Reference data: g (acceleration due to gravity) = 9.8 m / s2; ρ (density of mercury) = 13600 kg / m3.

SI system: h = 76 cm = 76 * 10-2 m = 0.76 m.

The pressure that will be produced by a column of mercury of a given height is determined by the formula: P = ρ * g * h = 13600 * 9.8 * 0.76 = 101 292.8 Pa ≈ 101.3 kPa.

Answer: a) A 76 cm column of mercury exerts a pressure of 101.3 Pa.
