Question

Methanol and ethanol form nearly an ideal solution at 300 k a solution is made by mixing 32g methanol and 23 g ethanol at 300 K calculate the partial pressure of its constituent and the total pressure all the solution (at 300 k pc3 o h is equal to 90 mm h and PC to h v o h is equal to 51 mmhg)

it make help you....

pls mark it brain list.....

Answer 2

Concept Introduction:-

Methanol $(CH_3OH)$, the most basic form of alcohol is methyl alcohol, sometimes referred as wood alcohol and wood spirit of the alcohols, which are a group of chemical compounds.

Given Information:-

We have been given that Methanol and ethanol form nearly an ideal solution at $300$ k a solution is made by mixing $32$ g methanol and $23$ g ethanol at $300$ K.

To Find:-

We have to find that the partial pressure of its constituent and the total pressure all the solution.

Solution:-

According to the problem

$\begin{aligned}&\mathrm{CH}_{3} \mathrm{OH}=\frac{32}{32}=1 \mathrm{~mole}\\&c_{2} H_{5} O H=\frac{23}{42}=0.5 \text { mole }\\&X_{A}=\frac{1}{1+0.5}\\&=\frac{1}{1.5}\\&=0.67\\X_B=\frac{0.5}{1+0.5}\\&=\frac{0.5}{1.5}\\&=0.34\\&P_{T}=x_{A} P_{A}+x_{B} P_{B}\\&=0.67 \times 90+0.34 \times 51\\&=60.3+17.34\\&=77.37 \mathrm{mmHg}\end{aligned}$

Final Answer:-

the partial pressure of its constituent and the total pressure all the solution is $77.37$ mmHg.
