A gas sample is attached to an open$-$ended mercury manometer, as shown below. The difference in heights of the mercury in the manometer is $24\mathrm{.}7cm$ when the atmospheric pressure is $0\mathrm{.}846$ atm. Given that density of mercury is $13\mathrm{.}6\frac{g}{m}L,$ the pressure of the enclosed gas is $?$torr.

Write your answer as $321$ torr $(3$ significant figures$)$
