Question

A sample of a gas weighing 15.1 g occupies 2.25 L at 1.75 atm and 20.0^{$\omicron $}C . If the empirical formula of the gas is NO₂, What is the molecular formula?

Quizplus · Accepted Answer

To find the molecular formula, first calculate the molar mass using the ideal gas law. The molar mass is approximately 92 g/mol, which matches the molar mass of N₂O₄, the molecular formula.
