It depends on that kind of catylst was used, and for that kind of experiment. Mainly catylsts absorb chemicals on there surface for reactions to take place on, now if at the end of the experiment not all the the chemicals unabosrb they will have an increase mass of that equal to the unaborsb chemicals.

Your concept is wrong. The amount of catalyst does not change after the experiment. Neither does the mass of the catalyst. Catalyst only speed up reactions, they do not take place in any reaction. Therefore, the amount and/ or mass of the catalyst does not change after the experiment.

A catalyst takes part in a reaction, usually by changing its oxidation state or by helping to weaken bonds in a reactant, but is always returned to its original form - and mass - at the end of a reaction.
Catalysts speed up reactions by providing an alternative pathway of lower activation energy.
