Answer:
C3H3O3
Step-by-step explanation:
To find its molecular formula, we simply use the empirical formula together with the molar mass. Firstly, we obtain the molar mass of the empirical formula CHO. His can be obtained by using the masses of the individual atoms. The masses are 12, 1 and 16 for carbon, hydrogen and oxygen respectively.
Hence: (12+[6+1)n = 88.12
29n = 88.12
n = 3
The molecular formula is thus C3H3O3
