C7H6O3............+........... C4H6O3 ----> C9H8O4 + CH3COOH
salicylic acid ....................aspirin
(Mr=138)......................... (Mr=180)
So besically, to work out the percentage atom economy of aspirin you have to divide the useful product (so in that case we are dividing salicylic acid to get the percentage mass of aspirin(of the useful product) by the mass of the reactants (aspirin)and then multiply by 100%to give you the percentage atom economy :)
So it is: (138/180) x 100 = 76.6

∙ 11y agoAspirin is C9H8O4, and 1 mole of any substance contains 6.02x1023 representative particles. Since aspirin has 9 carbon atoms per representative particle, the answer is (6.02x1023) times 9 = 5.418x1024 carbon atoms.

∙ 13y agoC9H8O4 is the formula of aspirin. ( lot of aspirin!)
25 grams C9H8O4 (1 mole C9H8O4/180.154 grams)(9 moles C/1 mole C9H8O4)(6.022 X 10^23/1 mole C)
= 7.5 X 10^23 atoms of carbon

Why is it important to use industrial reactions with a high atom economy?
Atom economy is the percentage of the "wanted" product(s) in a reaction against all of the other calculated "waste" product(s).
What atom or group of atoms makes aspirin a Bronsted-Lowry acid?
The carboxylic acid group or -COOH group makes it acidic
What is the difference between atom economy and percentage yield?
The percentage yield shows the percentage of the actual amount of product you got from the amount of product you ought to get. A reaction can have a high percentage yield while at the same time producing much waste. So as an alternative, the idea of atom economy was put forward as a better measure of a synthesis efficiency. Atom economy shows the percentage of the desired products from the total amount of reactants.
How do you calculate the atom economy?
Atom economy or atom utilization is simply the Mr or molecular weight of desired product formed divided by the Mr of all the reactants. Say we have a reaction A + B -----> C C + D ------> E AU = (Mr of E/(Mr of A + B + C)) x 100
What is the difference between aspirin to buffered aspirin?
Buffered aspirin has an added buffering agent so that it is easier on the stomach.

What is atom economy reaction?
The question itself makes no real sense. The Atom economy of a chemical reaction is calculated using the formula Atom economy = mass of useful product / mass of products x 100 This effectively gives the percentage of the mass of reactants turned into useful products thus allowing a calculation of waste from a given process.

What is the atom economy of ammonia?
The percentage yield of ammonia depends on the balance between the forward and backward reactions.

Industrial reactions with a high atom economy are economically important because?
Atom economy is the percentage of the "wanted" product(s) in a reaction against all of the other calculated "waste" product(s). The formula for atom economy is as follows:A.E.% = mass of wanted product/total mass of products x 100Industrial reactions clearly use vast amounts of chemical reactants and therefore there is a large quantity of waste products. These large quantities of waste would have a high environmental impact and as a result much effort and energy is required to dispose of them in a "green" way this in turn costs. So those reactions with a low atom economy produce a high percentage of waste thus costing large sums to dispose of "correctly".However, there are many more economical factors than simply disposing of the waste products. From an industrial point of view the chemicals used as reactants are bought and thus with a low atom economy large quantities of product are wasted along with the money that could have be gained if these chemicals had reacted into the desired product.Therefore, industrial reactions with a high atom economy are economically important because, a high atom economy means a high amount of the desired product, as there is more of this, more can be sold generating a higher profit.
