In one observation, the column in a mercury barometer (as is shown in Fig. 14.3.1a) has a measured height \( h \) of \( 740.35 \text{ mm} \). The temperature is \( -5.0^\circ\text{C} \), at which temperature the density of mercury \( \rho \) is \( 1.3608 \times 10^4 \text{ kg/m}^3 \). The free-fall acceleration \( g \) at the site of the barometer is \( 9.7835 \text{ m/s}^2 \). What is the atmospheric pressure at that site in pascals and in torr (which is the common unit for barometer readings)?
