When the PH is 7.0, the hydronium Ion Concentration is gotten as; [H3O+] = 1 × 10^(-7) M
<h3>How to find the Concentration of an Ion? </h3>
The formula to find the pH of an Ion concentration is;
pH = - log [H3O+]
where;
[H3O+] is the molar concentration of hydronium ion.
We are told that the pH is 8.0. Thus;
8.0 = - log [H3O+]
10^(-8) = [H3O+]
[H3O+] = 1 × 10^(-8) M
Thus, when pH = 7.0, we have;
7.0 = - log [H3O+]
[H3O+] = 1 × 10^(-7) M
Complete question is;
When the fish-tank water has a pH of 8.0, the hydronium ion concentration is 1.0 × 10-8 mole per liter. What is the hydronium ion concentration when the water has a pH of 7.0?

Answer:
The mean will rise drastically. The median will have very little change if at all.
A meaning other than the literal meaning
A figurative meaning has to do with the words which are used by an author to create a different meaning of a word so that he would have to observe closely to get the real meaning.
Some examples of a figurative expression include:
irony
Personification
Metaphor
Oxymoron
Sarcasm
Hyperbole, etc
With the aforementioned figurative expressions, an author can use them to create dramatic effect, etc
Answer : Mass
Explanation: The first Law states that all objects have inertia. The more mass an object has, the greater its inertia and the more force it takes to change its state of motion. The amount of inertia an object has depends on its mass - which is roughly the amount of material present in the object.
