I tried to find an answer to this from the Internet but couldn't. I did find that a 25 m tall tree can take over 20 000 kg of carbon dioxide out from the air per year, but how much dust? We made a bet so can you help me to find the answer?

It depends on the type of tree(s), location of the tree(s), the dust load flowing in the direction etc. The trees with closely bunched leaves (as in Polyalthia spp) would naturally trap / filter more dust, than ones with sparse and distantly placed leaves. The trees overlooking highways with heavy traffic would be laden with much dust. Trees in urban areas maintained clean would have least dust collection.
But all these are logical expectations and a quantification may be attempted as follows:
1. wash off all dust on the chosen tree to remove all the dust at 6 am
2. Again spray water on the same tree at 6 pm to collect the dust as solution,
3. have them filtered in large lab filter papers
4. dry the collection on the paper, weigh and estimate the quantity of dust trapped .
This data will be applicable for the particular tree, for the particular location, for 12 hours of a day in the relevent month (windy months may give greater collection).

Please review your research. I am not an expert on trees and the amount of carbon that they can remove from the environment in a year, but I do know that 20,000 kg is several magnitudes too large. It would probably be closer to 20,000 g per year of carbon dioxide.
As far as dust, most particulate will be washed out in the next rain. While certain trees would be slightly more effective than others by providing more surface area for the dust to land on, the next rain will wash it down to the ground anyway.

They don'e remove dust other than what lands on them. They use the carbon dioxide to make carbohydrates out of, but they do not take up dust. I hope you bet on zero.

I don't think tree's remove dust from the air. There not vacumn cleaners.
