In the dissolved$-$oxygen $($DO$)$ test the following data is reported:

Volume used in titration $=7\mathrm{.}52mL$ Thiosulfate Sodium

Temperature $=23C$

Atmospheric Pressure $=25\mathrm{.}33$ in $Hg$

Dissolved Oxygen $($Polarographic Method$)=6\mathrm{.}40$

Determine $\%$ error in the prediction of Dissolved Oxygen concentration. Estimate the chlorinity from table$).$ Equations from appendix.

Use Chl $($chlorinity$)$ from tables $=13\mathrm{.}7$
