Answer:

6.75%.

Explanation:

Dado que se mezclan 20 cc de solución de ácido sulfúrico al 6% v/v, con 12 cc de solución del mismo ácido al 8% v/v, para determinar la concentración de la solución resultante se debe realizar el siguiente cálculo:

20 x 0.06 + 12 x 0.08 = X

1.2 + 0.96 = X

2.16 = X

32 = 100

2.16 = X

2.16 x 100 / 32 = X

216 / 32 = X

6.75 = X

Así, la concentración de la solución resultante es del 6.75%.

How do i answer the question
sleet_krkn [62]
Well, your question is "How" do you answer the question, so I won't give you the answers (because I have no clue anyways)

Your simply answer 7-15 by filling in the missing word in the box. The sentences are missing words, and you have to find the correct form of that word that fits the sentence and makes it complete. In spanish, of course.
~Hope this helps!
