PORCENTAJE VOLUMEN A VOLUMEN ( % v/v)

EXPRESION ANALITICA:     % v/v= mililitros de soluto                 
                                                                                                 X 100
                                                             mililitros de solucion


EJEMPLO:
                         
                    DATOS:

                                 % v/v HCl= ?                  VHCl= 5mL                                  VH2O= 100mL


SOLUCION:  
                      % v/v HCl=   VCHl                X100
                                            V disolucion

V disolucion= VHCl + VH2O= 5mL+ 100mL= 105mL

% v/v HCl= 5mL                
                                            X 100= 4.8%
                   105mL


2º EJEMPLO

DATOS:
      V acido acetico= ? V disolucion= 300 mL    % v/v acido acetico= 20%


SOLUCION:
   
                  V acido acetico=  ( % acido acetico)  ( V disolucion) = (20%)(30mL)= 60mL
                                                                                 100%                       100%
