The formula of the asprin is C₉H₈O₄. Asprin is also called as acetylsalicylic acid
which is used as a drug in medical treatments. It is a synthetic derivative of
salicylic acid which is extracted from willow bark.<span>
<span>As the functional groups, asprin has 3 groups as
carboxylic acid group, ester group and aromatic ring. The structure is as the

Explanation:
According to the Handerson equation,
pH =
or, pH =
Putting the given values into the above equation as follows.
pH =
5.0 = 6.0 + log \frac{\text{conjugate base}}{\text{acid}}[/tex]
= -1.0
or,
= 0.1
Therefore, we can conclude that molar ratios of conjugate base to weak acid for given solution is 0.1.
<u>Answer:</u> The mass of carbon dioxide formed in the reaction is 269 grams.
<u>Explanation:</u>
Law of conservation of mass states that mass can neither be created nor be destroyed but it can only be transformed from one form to another form.
This also means that total mass on the reactant side must be equal to the total mass on the product side.
The chemical equation for the decomposition of calcium carbonate follows:
Let the mass of carbon dioxide be 'x' grams
We are given:
Mass of calcium carbonate = 612 grams
Mass of CaO = 343 grams
Total mass on reactant side = 612 g
Total mass on product side = [343 + x] g
So, by applying law of conservation of mass, we get:
Hence, the mass of carbon dioxide formed in the reaction is 269 grams.
