We're being asked to calculate the pH of a solution made by mixing 100.0 mL of 0.10 M HNO3, 50.0 mL of 0.20 M HCl, and 100.0 mL of water.

• pH

▪ pH stands for the negative logarithmic function of hydronium ion concentration
can be calculated using the following equation:

Take note that:         [H+] = [H3O+]

We're going to calculate the pH of the solution using the following steps:

Step 1. Calculate the total moles of H3O+ ions in the solution.
Step 2. Calculate the total volume of the solution (in L).
Step 3. Calculate the total concentration of H3O+ ions in the solution.
Step 4. Calculate the pH of the solution.
