A cylinder containing nitrogen gas and same liquid water at a temperature of `25^(@)C`. The total pressure n the cylinder is 600 mm. The piston is moved into the cylinder til the volume is halved keeping the temperature constant. If the aqueous tension at `25^(@)C` is 23.8 mm, calculate the final total pressure in the cylinder.

Explanation

`p_(N_(2))=600-23.8=576.2mm`
`p_(N_(2))` (after piston is moved) `=2xx576.2=1152.4mm`
total pressure `=1152.4+23.8=1176.8` mm
