2.5 mol will have 2.5 times Avogadro's number of molecules.
Each molecule consists of 2 hydrogen atoms.
That should give you what you need to calculate the answer.

Do a web search for Avogadro's number, if you don't know its value.

well it would be 2.5 moles which would equate to about 1.505x10^24 atoms.
