A student carried out a titration using H2SO4 and KOH.  The balanced equation for the reaction is: H2SO4 (aq) + 2 KOH (aq)  -->  K2SO4 (aq)  +  2 H2O (l) The student determined that 0.227 mol KOH were used in the reaction.  How many moles of H2SO4 would have been needed to react with all of this KOH? Enter a numerical value in the correct number of significant figures.  Do not enter units and do not use scientific notation.
