Question

1. A 30.0 L gas cylinder at 38 °C is filled with 3.33 moles of carbon dioxide and 3.66 moles of nitrogen. Calculate the total pressure, as well as the mole fractions and partial pressures of carbon dioxide and nitrogen, in the cylinder.

Answer 1

1 answer is
- 0 Given Volume (V) = 30L Temperature (T) = 78€ = 38 +273= 311K moles of cqz = nege = 3.33 moles of N = 2 = 3.66 we know the ideal gas equation PV = nRT) > P = 0. RT 3 Para Pest now). RT R- gas constant = 0.087) L. atos Komol substitute all the values in the above equation Pieter = (3-33+ 366) molés.

Mole fractions? (x) Mole fraction = number of moles of gas Total moles of mixture no = 3.66, Total moles = 6.99 neq= 3.33, Yeager get = 0.476 3.33 6-99 = 0.476 6.99 " Mole fraction of CO = 0.476 and Ng = 0.524 partial pressures! Partial pressure (P) = Total pressure x mole fraction .: Peer = YesyPraten = 16.476) (5.95 atm) = 2.83 atm Pigs = x^s. Ptotal = (0.526) (5.95 atm) = 3.laatm a partial pressures of coa = 2.83 atm Na = 3. laatm
