Answer:
10 liters.
Step-by-step explanation:
Let the volume of 2% acid be x liters.
Then the volume of the 8% solution will be (x + 30) liters.
Work in amounts of pure acid: amount of acid in the 10% solution = 30 * 0.1
= 3. So we have the equation:
0.02x + 3 = 0.08(x + 30)
0.08x - 0.02x = 3 - 0.08*30
0.06x = 0.6
x = 10
So the answer is 10 liter of the 2% solution.

<h3>What is a subject-verb agreement?</h3>
The matching of a sentence's subject and verb in tense, aspect, and mood, also known as the number, person, and gender, is known as subject-verb agreement or "subject-verb concord".
Only the verb be altered depending on whether the sentence is in the first, second, or third person in English, which does not employ grammatical gender aside from pronouns. Accordingly, the majority of subject-verb agreements in English are quantified: if the subject is singular, the verb must also be singular; if the subject is plural, the verb must also be many. Even this, though, can be perplexing because the first-person singular ("I climb the fence") and first-person plural ("We climb the fence") verb tenses are the same.
