In my experiment I heated some oxide of tin, in order to figure out its empirical formula.
How would the empirical formula be affected if the oxide was not heated to dryness?
If some oxide splattered out of the container, how would this affect the calculated ration of the number of moles of oxygen to the number of moles of tin?
You would be recording a mass for Sn highter than you should, as it contains H2O
