Explanation / Answer

C%     =   12*wt of CO2*100/44*wt of compound

             = 12*4.122*100/44*1.376    = 81.69%

H%     = 2* wt of H2O *100/18*wt of compound

            = 2*1.35*100/18*1.376   = 10.9%

O%     = 100-(C%+ H%)

          = 100-(81.69+10.9)

           = 7.41%

Element            %                          A.Wt                 Relative number             simple ration

C                      81.69                    12                    81.69/12 = 6.8075            6.8075/0.463 = 15

H                       10.9                      1                      10.9/1     = 10.9                  10.9/0.463     = 24

O                        7.41                    16                     7.41/16    = 0.463             0.463/0.463   = 1

The empirical formula = C15H24O
