<u>Answer:</u> The number of moles of gas present are 0.390 moles
<u>Explanation:</u>
To calculate the number of moles of gas, we use the equation given by ideal gas which follows:
where,
P = pressure of the gas = 0.868 atm
V = Volume of the gas = 11 L
T = Temperature of the gas =
R = Gas constant =
n = number of moles of gas = ?
Putting values in above equation, we get:
Hence, the number of moles of gas present are 0.390 moles
