A polymeric substance, tetrafluoroethylene, can be represented by the formula \( \left(\mathrm{C}_{2} \mathrm{~F}_{4}\right)_{x} \), where \( x \) is a large number. The material was prepared by polymerizing \( \mathrm{C}_{2} \mathrm{~F}_{4} \) in the presence of a sulphurbearing catalyst that serves as a nucleus upon which the polymer grew. The final product was found to contain \( 0.012 \% \mathrm{~S} \). What is the value of \( x \), if each polymeric molecule contains one sulphur atom?
Assume that the catalyst contributes a negligible amount to the total mass of the polymer. ( \( F=19 \), \( \mathrm{S}=32) \)
