If the Molar Mass of Iron is 55.85 g/mol, and the Molar Mass of Copper is 63.55, calculate how many moles of Iron were consumed in your reaction, and how many moles of Copper were produced?

I'm learning about the periodic tables and what each subject's configuration is. for example, hydrogen is 1s^1, but i don't understand how you get that. can someone me understand how to figure out how to figure this out? sorry if the question makes no sense, but it would really a lot if you could me understand! you so much if you can!
