When a barometer reads an atmospheric pressure as $734 \mathrm{~mm}$ of $\mathrm{Hg}$, what is the pressure in $\mathrm{N} / \mathrm{m}^{2} ?$ (The density of mercury is $13,600 \mathrm{~kg} / \mathrm{m}^{3} .$ )
Find the value of atmospheric pressure when the height of the mercury column in a barometer is 76.0 cm. Density of mercury is 3 13.6 10 Ć kg/m^3.
