The pH of a solution of sulphuric acid that has hydronium ion concentration is 4.26.
<h3>How do we calculate pH?</h3>
pH of any solution is define as the negative logarithm of the concentration of H⁺ ion present in any solution, i.e.
pH = -log[H⁺]
In the question, it is given that:
Concentration of hydronium ion or H⁺ ion = 5.45×10⁻⁵ M
So, pH will be:
pH = -log(5.45×10⁻⁵)
pH = -(-4.26)
pH = 4.26
Hence required pH is 4.26.

The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
<h3>What is atomic mass of an element?</h3>
Atomic mass of an element is the sum of the masses of the protons and neutrons in the nucleus of an atom.
<h3>Why is the atomic mass of Nitrogen-14 and Nitrogen-15 different?</h3>
The difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is due to the difference in the number of neutrons.
Nitogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
Therefore, the difference in the mass of the Nitrogen-14 and Nitrogen-15 atom is because nitrogen-15 has 8 neutrons while nitrogen-14 has 7 neutrons.
