D&D 5E Tomb of Horrors: XPs for every room

[Zoltar the Sage]

During the ToH discussion I started running 5e ToH (Chris Perkins conversion) and I was thinking to assign XPs for every room that PCs will "resolve" but I've no idea on how much could be the reward. It's a 10th level party.
Have you any suggestions?

Regards

Decide what pace you want the PCs to advance. By the time they survive Tomb of Horrors, what level should they be? Take all the combat encounters and then use the non-combat encounters to get them there. Divide by the total.

If they are completionists give them a bonus.
