A candle flame produces easily seen specks of soot near the edges of the flame, especially when the candle is moved. A piece of glass held over a candle flame will become coated with soot, which is the result of the incomplete combustion of candle wax. Elemental analysis of a compound extracted from a sample of this soot gave these results: $92.26 \% \mathrm{C}$ and $7.74 \%$ H by mass. Calculate the empirical formula of the compound.
