How many moles of Oxygen (O2) gas can be stored in a standard gas cylinder at a temperature of 20.0o C and a pressure of 15200 kPa? The volume of a standard gas cylinder is 47 Liters

Respuesta :

Answer: Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of [tex]20.0^0C[/tex] and a pressure of 15200 kPa

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = 15200 kPa =150 atm   (1kPa=0.0098atm)

V = Volume of gas = 47 L

n = number of moles = ?

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]20.0^0C=(20.0+273)K=293.0K[/tex]

[tex]n=\frac{PV}{RT}[/tex]

[tex]n=\frac{150atm\times 47L}{0.0821L atm/K mol\times 293.0K}=293moles[/tex]

Thus 293 moles of Oxygen gas can be stored in a standard gas cylinder at a temperature of [tex]20.0^0C[/tex] and a pressure of 15200 kPa
