Observam ca solutia a fost diluata, deoarece si-a micsorat concentratia cu 16%.
calculam md din solutia finala:
md=c*ms/100=20*50/100=10g HCl
md initial=md final, caci prin diluare, masa de acid nu se modifica
cinitial=md*100/msinitial => msinitial=10*100/36=27,77g solutie
Vs=ms/d=27,777/1,18=23,54ml solutie HCl
