Gas equations

Ozone molecules in the stratosphere absorb much of the harmful radiation from the sun. the temp. and the pressure of ozone in the stratosphere are 250 K and 1.0*10^-3 atm. How many ozone molecules are present in 1.0 L of air under these conditions?

Will Pressure Exceed Capacity?

Question: A metal tank of volume 75.5 L will burst if the pressure in it exceeds 50.0 atm. Will this pressure be exceeded by 82.0 moles of a gas in it at 25 degrees Celsius?
