Consentration question(basic chemistry)

[transgalactic]

we desolve 3.576 gr of KCL in water
and complement the volume to 200ml
what is the concentration of the solution??

Do you understand what concentration actually is? It measures the amount of ssomething in some volume. You could measure it in moles per litre, grams per mL etc. Think about what it means and see if you can try to solve it yourself.

i know how to calculate the number of moles in 3.576 gr of KCL
but i don't know what's the volume of that in the solution?

i could calculate the number of moles per litter

Good! Then you can calculate Molarity, which is moles of solute in 1 liter of solution.
