Question

A cylinder, with a piston pressing down with a constant pressure, is filled with 2.20 moles of a gas (n1), and its volume is 50.0 L (V1). If 0.800 mole of gas leak out, and the pressure and temperature remain the same, what is the final volume of the gas inside the cylinder?

Given. pressure is maintained constant with the help of piston Initial moles = 2.20 moles of gas - n1=2.20 - Initial volume = 50.0L (V1 = 50.01) same Also given; 0.800 mole of gas leak out, pressure and temperature remain the Hence; n2 = n1-0.500 = 2.20-0.800 = 1.400 final mole = 1.400 Applying PV=nRT | Ideal gas equation - we get PIV = P2 V2 I niti M2T2 given; T1=T2; PER Theretoner = 12 n AM 1 50.0 V2 2.20 1.40 12 50.0 X 1.40 2.20 1/2 = 31.822 inal volume of the gas inside the = 3182L cylinder
