  1. 1 Atm supports a column of mercury 760 mm high, so, A column of 1.10 m = 1100 mm => P = 1100 mm/760 mm/Atm = 1.5 Atm (2 Sig. Figs)

    A column of mercury in a barometer is 767.3 mm Hg high. Note, that in order for the pressures to be equal, density and height of a column are inversely proportional, therefore, (den1)(h1)=(den2)(h2). The density of mercury is 13.6
