A `250 mL` water solution containing `8.19 g` of sodium chloride at `300 K` is separated from pure water by means of a semi-permeable membrane. The pressure that must be applied above this solution in order to just prevent osmosis is "(`R=0.0821 L atm mol^(-1) K^(-1)`)"
a.13.80 atm ,b.27.58 atm ,c.23.34 atm ,d.9.80 atm

Text Solution

b.`pi=ixxCxxRxxT` [for NaCl,i=2]
=`2xx(8.19/58.5)xx(1000xx250)xx0.0821xx300=27.58 atm`
