Answer :
To simplify, we need to assume that the gas is an ideal gas so we can use the equation PV=nRT where P is pressure, V is volume, n is the number of moles, R is the universal gas constant and T is the temperature. We can calculate as follows:
PV = nRT
n = PV / RT
n = 10130(60) / 8.314 (200+273.15)
n = 154.51 mol argon gas
PV = nRT
n = PV / RT
n = 10130(60) / 8.314 (200+273.15)
n = 154.51 mol argon gas
