Molecular formula is a chemical formula that gives the total number of atoms of the elements in a compound.
Empirical formula is a chemical formula that gives the relative proportions of elements in a compound but not the actual number of atoms of elements in a compound.
In this problem, we are provided with mass percentages of H, N and O. The molar mass if given (50 g/mol). We will calculate the empirical formula through these steps:
A compound composed of 2.1% H, 29.8% N, and 68.1% O has a molar mass of approximately 50 g/mol.
