For a gaseous mixture of and with an average molecular weight of 36, which is/are correct? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question
Question
For a gaseous mixture of $CO$ and $CO_2$ with an average molecular weight of 36, which is/are correct?
Answer: A,B,C,D
💡 Solution & Explanation
$36 = 28x + 44(1-x) \Rightarrow 36 = 28x + 44 - 44x \Rightarrow 16x = 8 \Rightarrow x = 0.5$. <br>$\chi_{CO} = \chi_{CO_2} = 0.5$. <br>Mole/Volume ratio is $1:1$. <br>$\text{Mass ratio} = (0.5 \times 28) : (0.5 \times 44) = 14:22 = 7:11$.
