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 temp

Lapatulllka [165]

Answer: 101 moles of oxygen are contained in the tank

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 204.047 atm

V = Volume of gas = 12.0 L

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $22.0^0C=(22.0+273)K=295K$

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

$n=\frac{204.047atm\times 12.0L}{0.0821 L atm/K mol\times 295K}=101moles$

Thus 101 moles of oxygen are contained in the tank
