A solution is prepared by adding 0.0231moles of H3O+ ions to 3.33L of water. What is the pH of this solution

2.15

Explanation:

For this question, we have to remember the pH formula:

By definition, the pH value is calculated when we do the -Log of the concentration of the hydronium ions (). So, the next step is the calculation of the concentration of the hydronium ions. For this, we have to use the molarity formula:

We already know the number of moles (0.0231 moles) and the volume (3.33 L). So, we can plug the values into the molarity formula:

With this value, now we can calculate the pH value:

The pH would be 2.15

I hope it helps!

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

i think it's c. i'm not sure but i think so.
