5. A 4.44 L container holds 0.481 mol of O2 at 22.6°C. What is the pressure of the tank?
mamaluj [8]

Answer:  The pressure of the tank will be 2.63 atm

Explanation:

According to ideal gas equation:

PV=nRT

P = pressure of gas = ?

V = Volume of gas = 4.44 L

n = number of moles = 0.481

R = gas constant =0.0821Latm/Kmol

T =temperature =22.6^0C=(22.6+273)K=295.6K

P=\frac{nRT}{V}

P=\frac{0.481mol\times 0.0821Latm/K mol\times 295.6K}{4.44L}=2.63atm

The pressure of the tank will be 2.63 atm
