Question

(JEE Advanced 2016) A gaseous mixture contains equal masses of $He, CH_4$ and $SO_2$. Which of the following is/are correct?

Answer: A,B,C,D

💡 Solution & Explanation

Let mass be $m$. <br>$\text{Moles } He = m/4 = 16m/64$. <br>$\text{Moles } CH_4 = m/16 = 4m/64$. <br>$\text{Moles } SO_2 = m/64$. <br>Ratio $16:4:1$. Highest moles = highest pressure. Lowest moles = lowest mole fraction.
