Answer to Question #348205 in General Chemistry for Ann

Question

Calculate the pressure in a 212 Liter tank containing 23.3 kg of argon gas at 25°C? ( atomic weight Ar - 40 )

Answer 1

V = 212 l

T = 25°C =298 K

M(Ar) = 40 g/mol

R = 8,31

n(Ar) = m / M = 23300 / 40= 582,5 mol

P = nRT / V = 582,5 *8,31*298/212= 6804,2

Answer: 6804,2 kPa
