Series 100 contains carbon, hydrogen and oxygen, and has a molecular weight of 136 g/mol. In the combustion of a 5.000 g sample, 12.943 g of Co, and 2.655 g H2O were produced. From the above data, calculate the empirical and molecular formulas of your unknown sample. Use the following atomic weights: C = 12.01 H = 1.01 0 = 16.00 N = 14.01
