You can use fractional distillation which is when you a liquid from a mixture of two or more liquids. we can use their boiling points, alcohol has a boils at 87 celsius which is lower than waters boiling point, 100 celsius. when bringing the mixture to a boil, alcohol will escape first and be trapped and distilled. when the alcohol is still boiling the temp stays at 87 and doesnt rise. the temp only rises when the alcohol evaporates.

Calculate the pressure of the CO₂ (g) in the container at 425 K.

Elanso [62]

The pressure of the CO₂ = 0.995 atm

<h3>Further explanation</h3>

The complete question

<em>A student is doing experiments with CO2(g). Originally, a sample of gas is in a rigid container at 299K and 0.70 atm. The student increases the temperature of the CO2(g) in the container to 425K.</em>

<em>Calculate the pressure of the CO₂ (g) in the container at 425 K.</em>

Gay Lussac's Law

When the volume is not changed, the gas pressure is proportional to its absolute temperature

$\tt \dfrac{P_1}{T_1}=\dfrac{P_2}{T_2}$

P₁=0.7 atm

T₁=299 K

T₂=425 K

$\tt P_2=\dfrac{P_1\times T_2}{T_1}\\\\P_2=\dfrac{0.7\times 425}{299}=0.995 `atm$
