Use the pressure equation $($p$=$hdg$)$ to calculate the mercury equivalent of the height of the aqueous column $($e$.$g$.$ the height of a mercury column that would support the same pressure supported by the water column$).$ The density of mercury is $13\mathrm{.}6$ g$/$cm$3$ and the density of water is $1\mathrm{.}00$ g$/$cm$3.$ The pressure equation states that the pressure of the gas mixture at the surface of the aqueous column of liquid is equivalent to the product of the height of the liquid column, the density of the liquid and its acceleration due to gravity $($the gravitational constant$).$

$3.$ The vapor pressure of water at the observed temperature can be calculated using the data table and interpolation method described in Determination of the Faraday Constant Pre$-$lab Preparation document.
