હવે,  \(\frac{{{\text{P}}^{o}}\text{- }{{\text{P}}_{\text{s}}}}{{{\text{P}}_{\text{s}}}}=\frac{w\times M}{m\times W}\) \(=\left( \frac{w}{m\times W}\times 1000 \right)\frac{M}{1000}\)

\(\left( {\frac{{100\, - \,\,98}}{{98}}} \right)\,\, = \) મોલારીટી \(\,\, \times \,\,\frac{{18}}{{1000}}\)

મોલારિટી \( = \,\,\frac{2}{{98}}\,\, \times \,\,\frac{{1000}}{{18}}\,\, = \,\,1.133\)
