Which of the following diatomic elements would have a mass of 19.08 grams stored in a 3.82 L container at 3,632 mm Hg and 100°C?

Question

Quizplus · Accepted Answer

The ideal gas law can be used to calculate the number of moles of gas in the container:PV = nRTn = PV/RT = (3,632 mmHg * 3.82 L) / (62.36 L mmHg/mol K * 373 K) = 0.225 molThe mass of the gas can be calculated by multiplying the number of moles by the molar mass:mass = n * molar mass = 0.225 mol * 32 g/mol = 19.08 gTherefore, the diatomic element with a mass of 19.08 grams stored in a 3.82 L container at 3,632 mm Hg and 100°C is O2.
