What is the mole of O3?
The molar mass of ozone is 48g as each oxygen atom has mass has 16g and there are three oxygen atoms. So one mole of ozone is equal to 48g. As we know, 1 mole of ozone contains 6.022×1023 molecules of ozone. Each ozone molecule has three oxygen atoms.
How do you calculate moles of ozone?
Then you have X/M(O3) moles of ozone per cubic metre in the tank (where M(O3) is the molar mass of ozone in g). The ideal gas law lets you determine the molar density N (moles per cubic metre). The ozone mole fraction then is X/M(O3)/N.
What is the mass of 0.5 mole of o3 molecules?
∴ 0.5 mole of ozoneO3 = 0.5 × 48 /1 = 24 g.
