Answer: The pressure will be 18.05 atm.
Explanation: Expression for ideal gas equation is :
[tex]PV=nRT[/tex]
where,
P = Pressure of the gas = ? atm
V = Volume of the gas = 0.333L
n = Number of moles of gas = 0.250 moles
R = Universal gas constant = [tex]0.082057\text{ L atm }mol^{-1}K^{-1}[/tex]
T = temperature of the gas = 20°C = (273 + 20)K = 293K
Putting values in above equation, we get:
[tex]P\times 0.333L=0.250mol\times 0.082057\text{ L atm }mol^{-1}K^{-1}\times 293K[/tex]
P = 18.05 atm
