Yes, it is incorrect.
Step 1, assume you have a 100g sample of the compound.
This now means you know you have 1.2g H, 14.3g C, 27.4 g Na and 57.1g O.
Determine how many moles that relates to for each compound, and then determine the molar ration of each.
Do not try and bother making it be a legitimate structure, this is the empirical formula. That means it is the smallest integer number ratio of the compounds, not what the actual compound is.
