A 5.00 L flask contains 0.02 moles oxygen at 22°C, what is its pressure, in kilopascals? What is the pressure in atm?
1 Answer
The pressure of the gas is 10 kPa or 0.1 atm.
This looks like the time to apply the Ideal Gas Law:
#color(blue)(|bar(ul(PV = nRT)|)# ,
where
#P# is the pressure#V# is the volume#n# is the number of moles#R# is the gas constant#T# is the temperature
We can rearrange the Ideal Gas Law to get
To calculate the pressure in atmospheres, repeat the calculation using the value
