Styrene's empirical formula is CH. When it is heated to 200°C, it is converted into a polymer, polystyrene, which has
excellent insulating properties. An experimental determination of the molar mass of styrene by a student has given
the value of 103 + 4 g/mol. What is the molecular formula of styrene?
