Atom economy of aspirin

Answer 1

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

:)))

Answer 2

The atom economy of aspirin synthesis is relatively high, around 90%. This means that about 90% of the reactant atoms are found in the final product, while only around 10% are considered waste. This efficiency is one of the reasons why the synthesis of aspirin is considered to be environmentally friendly.

Answer 3

Aspirin 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.

Answer 4

C=carbon 9

H=hydrogen 8

O=oxygen 4

Answer 5

C9H8O4 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

Answer 6

Aspirin is a mostly used drug. Chemical formula for aspirin is C9H8O4. There are 9 carbon atoms in 1 aspirin molecule.

Answer 7

Asprin has C9H8O4 atoms in one molecule. 9 Carbon, 8 Hydrogen and 4 Oxygen. Add up the numbers: 9+8+4 = 21 atoms.

Answer 8

The molecule of aspirin (C9H8O4) contain 9 carbon atoms.
