Question

cylinder with a moveable piston contains 0.77 mol of gas and has a volume of 339 mL. Part A What will its volume be it an additional 0.25 mol of gas is added to the cylinder? (Hint: The final number of moles is the sum of the initial number and the amount added.) Express your answer to two significant figures and include the appropriate unit PIA O v.

Answer 1

Volume of the Cylinder with a moveable piston is V = 339 mL. Number of moles of gas present in Cylinder ,=0.77 md, PART-A = After addition of 0.25 mol of gas, final number of moles of gas na = (0.77 +0.25) moles. A n g = 1.02 molesa Let the final volume of gas after additio is v According to Avogado's law, van Cat Constant T&P) iz = Cinaya) = (839 m2 V= 449 mL ~ 450ML ... Fincel volume of gas [y2 = 4.5x10 m2

Initially, Volume of potato chip bag Vi = 595 mL Pressure P, = 760 mm of Hg Temperature Ti -(30°C+273) = 303K Finally, the pressure of the gas P2 = 423 mm of Hg Temperature T2 = (10°C +273) - 283k final Volume V₂ = ? From ideal gas equations, I BV for ame number & moles of gase 2 Conne) - 64 283 423 V = 998.46 m4
