  sodium azide,NaN3 is heated to 300degress and it rapidly decomposes into its elements.

  what volume of gas at room temperature and pressure would be produced by the decomposition of one mole of NaN3?

  Isn't it 3moles of N thus answer is 72dm^3?

  but y answer say it is 24dm^3?

  NaN3 ==> Na + 3/2N2

  3/2 x 24 = 36dm^3
