Which of the following is/are correct for a mixture of and in mass ratio ? — Mole Concept and Some Basic Concepts of Chemistry Chemistry Question

💡 Solution & Explanation

Let mass be $w$ ($O_2$) and $2w$ ($SO_2$). <br>$\text{Moles } O_2 = w/32$; $\text{Moles } SO_2 = 2w/64 = w/32$. <br>Ratio is $1:1$ for moles and molecules. <br>$\text{Atoms} = (1 \times 2) : (1 \times 3) = 2 : 3$. <br>By Dalton's law, mole ratio equals pressure ratio.
