At a pH of 7.3, what is the ratio of deprotonated imidazole to protonated imidazole for a histid

Name: At a pH of 7.3, what is the ratio of deprotonated imidazole to protonated imidazole for a histidine in the middle of a tripeptide (thus you can ignore the animo and carboxyl parts of the histidine)? (You should already know that the approximate pKa value for the His imidazole side chain is 6.0)
