Question
A cylinder is filled with a gaseous mixture containing equal masses of $CO$ and $N_2$. The partial pressure ratio ($P_{CO} : P_{N2}$) is:
Answer: D
💡 Solution & Explanation
Both $CO$ and $N_2$ have a molar mass of $28\text{ g/mol}$. Equal masses mean equal moles. Since moles are equal, partial pressures are equal. $P_{CO} = P_{N2}$.
