The empirical formula of ascorbic acid is C6H8O6.
<h3>Empirical formula</h3>
To calculate the empirical mass of a compound from the mass percentage of each element, the value of the<u> molar mass </u>of each element is used, which in this case corresponds to:
From this, we consider that the compound has 100 grams, so the number of moles of each element will be equal to:
Now, divide all the values found by the <u>smallest value</u>, to find the amount present in each element:
As you can see, the value of moles of hydrogen resulted in a decimal number, so it is necessary to multiply all values by a number in common until the three meet as integers:
So, the empirical formula of ascorbic acid is C6H8O6.
