To solve this question, we will simply use the gas law which is as follows:
PV = nRT where: P is the pressure = 100 kPa = 0.986923 atm V is the volume = 6.8 liters n is the required number of moles R is the gas constant = 0.08206 T is the temperature = 25 degree celcius (room temp) = <span>298 kelvin
Substitute in the above equation to get the number of moles as follows: </span> 0.986923 x 6.8 = n x 0.08206 x 298 n = 0.2744 moles
