an oxygen tank used for scuba diving has. avolume of 12.0 L .If the pressure of the tank is known to be 204.047 atm and the temperature is 22.0 C(295 K), how many moles of oxygen are contained in the tank

101 moles of oxygen are contained in the tank

Explanation:

According to ideal gas equation:

P = pressure of gas = 204.047  atm

V = Volume of gas = 12.0 L

n = number of moles  = ?

R = gas constant =

T =temperature =

Thus 101 moles of oxygen are contained in the tank

we need the questions , i may then you.
