Mercury has a density of 13600 kg/m3. At what depth in millimetres is the pressure in mercury equal to that of standard atmospheric pressure? (take std pressure= 101 Pa)

Answer 1

(rho)* g* h = 101*10^3 N/m^2

h = 0.758 m = 758 mm

The correct answer is 760 mm. There are too few significant figures in the input data
