Mods. Empirical Formula of an Oxide of Tin. Purpose: Within completing this lab, it was intended for the experimenter (student) to determine the empirical formula of an oxide of Tin by means of experimenting. This goal would be accomplished by finding the masses of the various substances experimented with, which 30 mesh tin, Tin Oxide, and Oxygen.
This information is used to calculate the empirical formula for a compound. The empirical formula is the simplest whole number ratio of atoms in a molecule. Example: Chemical analysis of a liquid shows that it is 60.0% Carbon, 13.4% Hydrogen, and 26.6% Oxygen by mass. Calculate the empirical formula of the substance.or example, if you have 0.50 moles of carbon atoms, how many atoms is that? 6.02 x 1023 atoms Carbon. 0.50 mol Carbon X -------------------------------------- = 3.01 x 1023 atoms Carbon. 1 mol Carbon. You can also convert from atoms to moles.
