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 k

larisa86 [58]

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

Explanation:

According to ideal gas equation:

$PV=nRT$

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

V = Volume of gas = 47 L

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $20.0^0C=(20.0+273)K=293.0K$

$n=\frac{PV}{RT}$

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

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