D i believe i’m sorry if i am wrong :)
Answer:
An example of a metal with an organic radical is: Pentamethylcyclopentadiene, which is the union between Zinc and an organic compound, where in order to obtain it there is a release of dihydrogen.
Another example is lead tetraethyl, it is a compound for industrial use, it is dangerous for the human body, toxic and can be used as fuel.
Explanation:
In radical chemistry a chemical species is called both organic and inorganic, which one of the most used examples is methyl, where it is a chemical structure that has one carbon and 4 hydrogens attached to this central carbon.
These chemical compounds when united with metals, release one of the unions that they have with hydrogens, it is because in reactions they release hydrogens.
Taking into account the definition of dilution, the new concentration of the solution is 0.2567 M.
First of all, you have to know that dilution is the reduction in concentration of a chemical in a solution, which is accomplished by simply adding more solvent to the solution at the same amount of solute.
In a dilution the amount of solute does not change, but as more solvent is added, the concentration of the solute decreases, as the volumeof the solution increases.
A dilution is mathematically expressed as:
Ci×Vi = Cf×Vf
where
-
Ci: initial concentration
- Vi: initial volume
- Cf: final concentration
- Vf: final volume
In this case, you know:
- Ci= 0.385 M
- Vi= 600 mL= 0.600 L (being 1000 mL= 1 L)
- Cf= ?
- Vf= 900 mL= 0.900 L
Replacing in the definition of dilution:
0.385 M× 0.600 L= Cf× 0.900 L
Solving:
Cf= (0.385 M× 0.600 L)÷ 0.900 L
Cf= 0.2567 M
In summary, the new concentration of the solution is 0.2567 M.

Avogadro's number is defined as the number of elementary particles (molecules, atoms, compounds, etc.) per mole of a substance. It is equal to 6.022×1023 mol-1 and is expressed as the symbol NA.
