(adsbygoogle = window.adsbygoogle || []).push({}); Assume we have a concentration of any specific material (in mg/M). Let's say for example: Ag (Z=47) with concentration 10 mg/M in water (H2O, Z=7.42).

How can I calculate the effective atomic number (Zeff.) for the silver-water mixture if the concentration of silver was 10 mg/M for example?

The only formula I know to calculate Zeff. is the following:

but it uses (fn) the fraction of the total number of electrons associated with each element, not the concentration in mg/M.

Is there any possible way to convert the concentration (in mg/M) into a fraction of total number of electrons for silver then calculate Zeff for the silver-water mixture mentioned above as an example?

Thanks in advance.
