Verified step by step guidance1
Identify that the compound is a binary molecular compound composed of two nonmetals: nitrogen and oxygen.
Recall the naming rules for binary molecular compounds: use prefixes to indicate the number of atoms of each element present in the molecule.
Determine the number of atoms of each element from the formula \(\mathrm{N}_2\mathrm{O}_5\): there are 2 nitrogen atoms and 5 oxygen atoms.
Apply the appropriate prefixes: 'di-' for 2 nitrogen atoms and 'penta-' for 5 oxygen atoms, and write the element names in order (nitrogen first, then oxygen).
Combine the prefixes and element names to form the correct name: 'Dinitrogen pentoxide'.
