A polystyrene, having the formula \( \mathrm{Br}_{3} \mathrm{C}_{6} \mathrm{H}_{3}\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)_{n} \) was prepared by heating styrene with tribromobenzoyl peroxide in the absence of air. If it was found to contain \( 10.46 \% \) bromine by weight, find the value of \( n \).
