Answer:

Both

Explanation:

Baking soda is the common name of  sodium bicarbonate or sodium hydrogen carbonate. Both the empirical and molecular formula of sodium bicaronate is NaHCO3 .

Baking soda is soluble in water and has a molar mass of almost Molar mass: 84.007 g/mol.

If we look at molecular formula of NaHCO3, it has molar ratio of 1:1:1:3 and we can say that every thing in this molar ratio make whole mass as : 23g +1 g +12 g+48 g= 84 grams.

Since we know that empirical formula demonstrates the simplest ratio of elements present in a compound and molecular formula demonstrates the total molar ratio of each element in a compound, hence we see that its empirical and molecular formulas both are already simple because they have simplest ratio which cannot be simplified further.

Hope it help!
