Chemistry: The Molecular Nature of Matter and Change

A long glass tube, sealed at one end, has an inner diameter of 10.0 $\mathrm{mm}$ . The tube is filled with water and inverted into a pail of water. If the atmospheric pressure is 755 $\mathrm{mmHg}$ , how high (in $\mathrm{mmH}_{2} \mathrm{O}$ ) is the column of water in the tube $(d \text { of } \mathrm{Hg}=13.5 \mathrm{g} / \mathrm{mL}$ $d$ of $\mathrm{H}_{2} \mathrm{O}=1.00 \mathrm{g} / \mathrm{mL} ) ?$
