Question

A cylindrical container of volume 4 . 0 × 10 - 3 m 3 contains one mole of hydrogen and two moles of carbon dioxide. Assume the temperature of the mixture is 400 K . The pressure of the mixture of gases is : [Take gas constant as 8 . 3 J mol - 1 K - 1

For gas A P A V = n A R T P A = ( 1 ) RT V for gas B P B V = n B RT P B = ( 2 ) R T V Now according to the Dalton's law of mixture, P = P A + P B = 3 R T V = 3 × 8 . 314 ( 400 ) 4 × 10 - 3 = 24 . 9 × 10 5 Pa
