The elemental mass percent composition of ascorbic acid (vitamin C ) is 40.92% C , 4.58% H , and 54.50% O . Determine the empiri

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:

$MM_C= 12g/mol\\MM_H=1g/mol\\MM_O=16g/mol$

From this, we consider that the compound has 100 grams, so the number of moles of each element will be equal to:

$C = \frac{40.92}{12} = 3.41 \\H = \frac{4.58}{1}=4.58\\ O =\frac{54.50}{16}=3.41$

Now, divide all the values found by the <u>smallest value</u>, to find the amount present in each element:

$C = \frac{3.41}{3.41} = 1\\ H = \frac{4.58}{3.41} = 1.34\\O = \frac{3.41}{3.41} = 1$

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:

$C = 1 \times 6 = 6\\H = 1.34 \times 6 = 8\\O = 6 \times 6 = 6$

So, the empirical formula of ascorbic acid is C6H8O6.

Answer:

It is possible not all of the water was evaporated from the sand, causing the recovered mass to be higher.

Explanation:

If not all the water is evaporated from the sand so the recovered mass to be higher than the sand from which more water is evaporated because evaporation of little amount of water causes less decrease in the recovered mass as compared to that sand from which more water is evaporated so more decrease occur in the recovered mass.
