46.When 0.1 mole of N_(2)O_(4)(g) was placed in a 1.0L flask at 400K and closed the following equilibrium is reached with a total pressure of 6 bar N_(2)O_(4)(g)=2NO_(2)(g) .Assuming ideal behaviour of the gases,the partial pressure of N_(2)O_(4)(g) at equilibrium in bar is (R=0.083 bar Lmol^(-1)K^(-1)) 1)3.32 2)9.32 3)0.664 4)2.68
