Calculate the number of moles of oxygen in a 12.5-l tank if the pressure is 25325 kpa and the temperature is 22°c

The ideal gas law states that:

where
p is the gas pressure
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas

For the gas in our problem:




If we plug the data into the equation, we can find the number of moles of the gas:
