What is the total pressure exerted by a mixture of of , of , and of gases in a vessel of capacity ke — States of Matter and Gaseous State Chemistry Question
Question
What is the total pressure exerted by a mixture of $7.0\text{ g}$ of $N_2$, $2.0\text{ g}$ of $H_2$, and $8.0\text{ g}$ of $SO_2$ gases in a vessel of $6\text{ L}$ capacity kept at $27^\circ\text{C}$?
Answer: D
💡 Solution & Explanation
Moles $n = (7/28) + (2/2) + (8/64) = 0.25 + 1 + 0.125 = 1.375\text{ mol}$. $P = nRT/V = (1.375 \times 0.08314 \times 300) / 6 = 5.71\text{ bar}$.
