C=md/ms*100=>md=25g HCl
2*36,5g.....74g...........111g......2*18g
2HCl + Ca(OH)2 => CaCl2 + 2H2O
25g......x=25,342g.......y=38g.....z=12,32876g
C=md/ms*100 => ms=md*100/C=25,342*100/25=101,37g sol. Ca(OH)2
md final = 25,342+38+25=88,342g
ms final =100+25,342+38+12,32876=175,67g
C final =mdf/msf*100=88,342/175,67*100=50,288%
