At 25°C and 449 mmHg,an unknown pure gas has a density of 0.676 g/L.Which of the following gases could be the unknown gas? A)Cl₂ B)C₃H₆ C)Cl₂O D)Ne E)N₂

Question

Quizplus · Accepted Answer

Using the Ideal Gas Law (PV=nRT) and the given density, we can calculate the molar mass of the unknown gas to be approximately 28 g/mol. Comparing this to the molar masses of the given gases, only nitrogen (N2) has a molar mass close to 28 g/mol. Therefore, the unknown gas is most likely nitrogen.
