ro= m/V---> m=ro x V
C/100=md/ms, c/100= md/ roxVs
-calculez masa de NaOH din solutie
10/100= md/100x1,115---> md=11,15g NaOH
-CALCULEz masa de acid care reactioneaza cu aceasta masa de baza
2NaOH+H2SO4---> Na2SO4 +H2O
2x40g...........98g
11,15g........m=13,66g H2SO4
-calculez masa de solutie de acid care contine dizolvate13,66g acid
6/100= 13.66/ 1,04Xms-------> calculeza ms !!!!!
