A storage tank contains 21.6kg of nitrogen (N2)at an absolute pressure of 3.65 atm. what will be the pressure if nitrogen is replaced by an equal mass of CO2 or carbon dioxide?..thanks!
From the ideal gas equation: PV = nRT we see that: P is directly proportional to n, the number of moles. And n = mass/Mr Thus: PMr/m = constant P₁Mr₁/m₁ = P₂Mr₂/m₂ 3.65 x 28 / 21.6 = P₂ x 44 / 21.6
