Question

Quizplus · Accepted Answer

The density of a gas is directly proportional to its molar mass and inversely proportional to its temperature and pressure. Among the given options, only Helium (He) has a molar mass of 4 g/mol (close to the given density value of 0.172 g/L). Additionally, the temperature and pressure values are not significant factors in determining the correct answer.
