Answer:
3.5
Step-by-step explanation:
Given : the hydronium ion concentration is 
in orange juice
To Find: what is the pH?
Solution :
Definition of pH : pH is the negative log of the molar hydrogen ion concentration
Formula of pH : - log [H+]
Since we are given H+ =
So, substituting this value in formula :
![pH = - log [3.4*10^{-4}]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A10%5E%7B-4%7D%5D)
![pH = - log [3.4*0.0001]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B3.4%2A0.0001%5D)
![pH = - log [0.00034]](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B0.00034%5D)
pH = 3.468≈3.5
Thus the pH is 3.5

Answer in fraction form = 8/25</h3><h3>
Answer in decimal form = 0.32</h3><h3>
Answer in percent form = 32%</h3>
We have 8 instances of "3" showing up out of 25 total rolls, which is where the fraction 8/25 comes from. Use your calculator to find that 8/25 = 0.32. Or you could multiply top and bottom of 8/25 by 4 to get 32/100 = 0.32 = 32%
