Answer : The pressure of the gas is, 14.925 atm
Solution :
using ideal gas equation,
[tex]PV=nRT[/tex]
where,
n = number of moles of gas = 0.3 mole
P = pressure of the gas = ?
T = temperature of the gas = [tex]30^oC=273+30=303K[/tex]
R = gas constant = 0.0821 Latm/moleK
V = volume of the gas = 0.5 L
Now put all the given values in the above equation, we get the pressure of the gas.
[tex]P\times (0.5L)=(0.3mole)\times (0.0821L.atm/mole.K)\times (303K)[/tex]
[tex]P=14.925atm[/tex]
Therefore, the pressure of the gas is, 14.925 atm
