Answer : The number of moles of gas present in container are, 0.1997 mole
Explanation :
Using ideal gas equation :
[tex]PV=nRT[/tex]
where,
n = number of moles of gas = ?
P = pressure of the gas = 1.30 atm
T = temperature of the gas = 274.27 K
R = gas constant = 0.0821 Latm/moleK
V = volume of gas = 3.46 L
Now put all the given values in the above equation, we get the moles of gas.
[tex](1.30atm)\times (3.46L)=n\times (0.0821L.atm/mole.K)\times (274.27K)[/tex]
[tex]n=0.1997mole[/tex]
Therefore, the number of moles of gas present in container are, 0.1997 mole
