What is the empirical formula of ascorbic acid, given that the pseudoformula is c3.407 h4.53 o3.406? ?

The empirical formula of ascorbic acid is C₃H₄O₃. Empirical formula is the smallest whole number ratios of elements in a compound.  

To get the empirical formula from mass percent data, the following steps are followed:

Applying steps 1 to 3 to the problem leads to the pseudoformula C₃₋₄₀₇H₄₋₅₃O₃₋₄₀₆ where equivalent number of moles are written as the temporary subscripts of the elements in the compound.

STEP 4: Divide the moles by the smallest mole value which in this case is 3.406.

STEP 5: Multiply the subscripts by a number that would give the smallest whole number ratio.  

Since the decimal is 1.33 it cannot be automatically rounded off to 1. It should be multiplied by 3 to get the smallest whole number.

NOTE: All subscripts must be multiplied by the same factor, 3.
