${\text{P}}$ કુલ ${\text{ = }}\left( {{p_A}^0 \times \frac{1}{2}} \right) + \left( {{p_B}^0 \times \frac{1}{2}} \right)$ $(\because \,\,1:1$ મોલ)

$\therefore 400 = \frac{{{P_A}^0}}{2} + \frac{{{P_B}^0}}{2}$

$\therefore \,\,\,\,{p_A}^0 + {p_B}^0 = 800$ ........... $(1)$

${\text{P}}$ કુલ ${\text{ =  }}{{\text{p}}_{\text{A}}}^{\text{0}}{{\text{X}}_{\text{A}}}{\text{  +  }}{{\text{p}}_{\text{B}}}^{\text{0}}{{\text{X}}_{\text{B}}}\,\,\,$

$\,\therefore \,\,\,350 = \left( {{p_A}^0 \times \frac{1}{3}} \right) + \left( {{p_B}^0 \times \frac{2}{3}} \right)$ ($\because \,\,1:2$ મોલ)

$\therefore 350 = \frac{{{p_A}^0}}{3} + \frac{{2{p_B}^0}}{3}\,$

$\,\therefore \,\,\,\,{p_A}^0 + 2{p_B}^0 = 1050$ ........... $(2)$

પરિણામ $(1)$  અને $(2)$  પરથી,${\text{P}}{{\text{A}}^{\text{0}}}{\text{  =  550}}$ મિમી, ${{\text{p}}_{\text{B}}}^{\text{0}}{\text{  =  250}}$ મિમી
