Consider the reaction h2so4 + 2 naoh -> na2so4 + 2h2o. in an acid-base tritration, the stoichiometric point happens when 27.43 ml of 0.2213 m naoh is added to a 30.23 ml portion of h2so4. what is the molar concentration of h2so4 expressed in m?

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!
