For a tungsten carbene (catalyst) binding to THF (ligand) at 25 oC in per-deuterotoluene solvent, the chemical shift of the unbound catalyst alpha hydrogen was determined to be 794.6 Hz and the peak for the fully bound catalyst alpha hydrogen was observed at 842.4 Hz. Furthermore, the binding constant (or formation constant) Kf was found to be 15.40 M-1. Given the following initial concentrations of catalyst and ligand, calculate the percent THF bound you would expect to see at 25 oC. Record your answer to the nearest tenths of a percent, as a number with no units (Ex. 3.4% ----> enter "3.4")
