since stoichiometry primarily has a multiplication and dividion steps, we follow the proper labeling of significant figures for them..

we choose the smallest significant figures in the problem. 

but when doing stoichiometric procedures, always make it a point not to round values duat each steps. usually what i can suggest is maintain a 4 decimal figures until the final answers. until then we can round up our answers to proper significant figures.


attached are more detailed steps 

hope this helps
