Calculate the number of mode of vibration CO2, NO2 and H2o.

Calculation the  Number of moe of vibration :-

For linear molecule formula is

                                                 3N-5

For Non-Linear molecule Formula is

                                                  3N-6



In  CO₂           3*3-5=4     (This is LInear molecule)

In NO₂           3*3-6=3     (This non-linear molecule)

In H₂O            3*3-6=3    (This is non linear molecule)
