what is the weight of ozone gas. ??? gr/cubic meter (at atmospheric pressure)?

Question

I need to calculate the volume of ozone generated by a 800 gr/Hr ozone generator.

Answer 1

Hi. From the web: "Ozone (O3) is a gas composed of 3 oxygen atoms combined in a ring. Ozone itself is a toxic, blue colored gas, which has a distinct odor, and is about one and a half times heavier than air."

Answer 2

Use the Ideal Gas Law for an approximation, breaking moles down into mass/molar mass. Assuming room temperature of 298K, it would give you volume in liters, which you would then divide by 1000 to get cubic meters.

PV = g/MM * RT
V = gRT/P*MM
V = 800g * 0.08206 * 298K / (1 atm * 48 g/mol)
V = 407.56 L = 0.408 m^3
