આપેલ છે કે:

$p_{{A}}^{0}=450 {~mm}$ ${Hg}$

$p_{{B}}^{0}=700 {~mm}$ ${Hg}$

$p_{\text {total }}=600 {~mm}$ ${Hg}$

રૉલોટની નિયમથી, આપેલ છે: $ \quad p_{{A}}=p_{{A}}^{0} \hspace{0.8mm} \chi_{{A}}$

$p_{{B}}=p_{{B}}^{0} \hspace{0.8mm} \chi_{{B}}=p_{{B}}^{0}\left(1-\chi_{{A}}\right)$

તો, કુલ દબાણ $p_{\text {total }}=p_{{A}}+p_{{B}}$

$\Rightarrow p_{\text {total }}=p_{{A}}^{0} \hspace{0.8mm} \chi_{{A}}+p_{{B}}^{0}\left(1-\chi_{{A}}\right)$

$\Rightarrow p_{\text {total }}=p_{{A}}^{0} \hspace{0.8mm} \chi_{{A}}+p_{{B}}^{0}-p_{{B}}^{0} \chi_{{A}}$

$\Rightarrow p_{\text {total }}=\left(p_{{A}}^{0}-p_{{B}}^{0}\right) \chi_{{A}}+p_{{B}}^{0}$

$\Rightarrow 600=(450-700) \chi_{{A}}+700$

$\Rightarrow-100=-250 \chi_{{A}}$

$\Rightarrow \chi_{{A}}=0.4$

તો, $\chi_{{B}}=1-\chi_{{A}}$

$\quad\quad\quad\quad\quad=1-0.4$

$\quad\quad\quad\quad\quad=0.6$

હવે, $p_{{A}}=p_{{A}}^{0} \hspace{0.8mm} \chi_{{A}}$

$\quad\quad\quad=450 \times 0.4$

$\quad\quad\quad=180 {~mm}$ ${Hg}$

$p_{{B}}=p_{{B}}^{0} \hspace{0.8mm} \chi_{{B}}$

$\quad=700 \times 0.6$

$\quad=420 {~mm}$ ${Hg}$

હવે, વેપર તળિયામાં:

તરલ A ની મોલ ભાગાંશ

$ \quad\quad\quad\quad\quad\quad\quad\quad\quad
\begin{aligned}
& =\frac{180}{180+420} \
& =\frac{180}{600} \
& =0.30
\end{aligned}
$

અને, તરલ B ની મોલ ભાગાંશ
$B=1-0.30$
