Question

A 1.0 mole sample of HNO3 is added to water. The final volume of the solution is 1.5 L. Calculate the pH of the Solution

Answer 1

Answer:
pH = 0.176

Step-by-step explanation:
To get the pH, we will first need to calculate the molarity of the solution as follows:
Molarity = number of moles of solute / liters of solution
We have:
number of moles of solute = 1 mole
number of liters of solution = 1.5 L
Therefore:
Molarity = 1 / 1.5 = 2/3

Now, we will get the pH value as follows:
pH value can be calculated by taking the negative log for the H+ concentration, which is in this case the same as molarity.
Therefore:
pH = -log [H+] = -log [2/3]
pH = 0.176

Hope this helps :)
