Atom economy of aspirin?
C7H6O3............+........... C4H6O3 ----> C9H8O4 + CH3COOHsalicylic 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:)))
What type of bonds are in an aspirin molecule?
Aspirin is an organic chemical acetylsalicylic acid and all organic compounds have covalent bonds (where electrons are shared between atoms)
What is the number of atoms of tin in 3 moles of tin?
The number of atoms is 18,066.10e23.
How can you calculate no of moles from no of atoms?
You divide the number of atoms by avagadro's number. Avagadro's number is 6.022x10^23 atoms/molecules / mole. The best way to remember this is by the units, atoms in each mole.
Does the number of atoms entering the reaction stay the same as the number put out by the reaction?
Chemical reactions do not change the number of atoms so yes, the number of atoms stays the same.
What are the elements and atoms in aspirin?
Pure aspirin is salicylic acid acetate, and therefore contains carbon, hydrogen, and oxygen atoms, which are also elements.
How many molecules of aspirin C9H8O4 are there in a 100.0 mg tablet of aspirin?
It depends on the mass of the tablet and the molar mass of the aspirin molecule itself, find out the mass in grams of one tablet, divide it by the sum of the number of neutrons and protons in one molecule of aspirin and it will give you the molar mass of the aspirin tablet.

How do you calculate atoms?
As in number? No of atoms = avagadros number (6.02X10^23) times number of mole of atoms
List the nameof each element that appears in the formula and give the number of atoms of each element present. HOOCC6H4OOCCH3?
Hydrogen - 8 Oxygen - 4 Carbon - 9 So, shorthand formula is C9H8O4 = aspirin
What are Atoms with the same number of protons are?
All atoms with the same number of protons are atoms of the same element. The number of protons is the atomic number of the element.
Every balanced chemical equation each side has the same number of?
same number of each element
Does the number of iron atoms in the reactants equal the number of iron atoms in the products?
no
What is the number of atoms of tin in 3 moles of tin?
The number of atoms is 18,066.10e23.
How many atoms do there be in sulfur?
there are 16 atoms in sulfur, because the number of atoms in an element is equal to its atomic number, which is the number at the top of the square which is bolded
How can you calculate no of moles from no of atoms?
You divide the number of atoms by avagadro's number. Avagadro's number is 6.022x10^23 atoms/molecules / mole. The best way to remember this is by the units, atoms in each mole.
