How to calculate atomic weight percentage for chemical. I don't know kindly help
This is a freshman chemistry student question-not a researcher's question. See some textbooks.
Dear Sir. Concerning your issue about the calculation of atomic weight percentage(at.wt.%). An atomic weight (relative atomic mass) of an element from a specified source is the ratio of the average mass per atom of the element to 1/12 of the mass of 12C" in its nuclear and electronic ground state. A sample of any element consists of one or more isotopes of that element. Each isotope is a different weight. The relative amounts of each isotope for any element represents the isotope distribution for that element. The atomic weight is the average of the isotope weights weighted for the isotope distribution and expressed on the 12C scale as mentioned above. Atomic Mass Calculations
Atomic Mass =
[[(mass of isotope) (%abundance) ] + [(mass of isotope) (%abundance)] + [….]] /100%
The equation continues on[….] based on the number of isotopes in the problem. I think the following below links may help you in your analysis:

Thank-you sir for replying with an answer

You need to recall perodic table & calculation of atomic weight. In respect to the compound weight from which it is to be calculated. By dividing the same you may able to know.
Weight of element in a cpd = amount in g /MW of cpd X AW of element
Hello There,
Have you been able to solve your atomic% or weight % problem, please?
If not, please let me know. I am here to help you.
Hi,
I need to know which material are you going to use as solvent.
If you use water as solvent. Because we know Ionic compounds dissolve in polar solvents.
So, 1 wt% Copper Sulphate will be a mixture of 1gm of copper Sulphate + 99 gm water.
To do so,
1.weight 1 gm copper Sulphate.
2. Weight a volumetric flax.
3. Cancel out the weight of volumetric flax.
4. Pour 1gm copper Sulphate in it.
4. Pour water in your beaker until it becomes 100 gm.
In brief : 1gm copper Sulphate + 99 gm water = 1 wt% copper Sulphate solution.
Note: you need to measure 99 gm water by weigh machine. It is not 99 ml water, although we know 99ml water equal to 99gm water.
If you need further explanation. I am really ready to help you by email or Skype or phone.
Science is for all. Let's make our society better by cooperating each other.
Your way of approach is really appreciable Mr.Sarkar.
Can you help me to calculate the 0.1 at% dopant concentration of Al(NO3)3·9H2O with 0.45 M titanium butoxide solution.
