Assume you mean hydrogen ion concentration.
Can be pH. But more technically H+ concentration is represented as [H+] with the units of molarity.
Whether you answer the question as pH or [H+] will depend on the level of chemistry that you are being taught.
If it is hydrogen then the answer will be only [H2]

pH = Hydrogen concentration? Well, not quite, but pH is a calculated by the minus logarithm of hydrogen ION concentration or [H+] IN AQUEOUS SOLUTION. Hydrogen concentration can be expressed as moles per litre of solution(Molarity) or moles per Kilogram of solution (Molality). It can also have the units of mass/volume such as grams/litre or so, but this would be rather odd, except in case hydrogen is dissolved as undisociated gas. Note that pH is a relative value which represents ONLY the ionic H+ concentration in aqueous solution. If the solution is of a different nature pH will not have a real meaning.

Hydrogen ion concentration is always expressed as pH.
