6) Determine la concentración de una solución que ha sido preparada añadiendo 80cc de agua a 320cc de solución alcohólica al 20%
Xelga [282]

Answer:

16% v/v es la nueva concentración de alcohol en la solución

Explanation:

El porcentaje volumen/volumen (% v/v) es definido como 100 veces la relación entre el volumen de soluto (Alcohol en este caso) y el volumen total de la solución (Agua + Alcohol). Para resolver esta pregunta necesitamos hallar el volumen de alcohol y el de agua:

<em>Volumen alcohol:</em>

320cc * (20cc etanol / 100cc) = 64cc etanol

<em>Volumen agua:</em>

80cc + (320cc-64cc) = 336cc agua

<em>% v/v:</em>

64cc / (336cc + 64cc) * 100

= 16% v/v es la nueva concentración de alcohol en la solución
