like a concentration of 1.0 M of NaCl what is cation and anion formed and the cation and anion concentration??
how do you find it??

When a compound like NaCl dissolves in water it forms Na+(aq) ions and Cl-(aq) ions. Cations are positively charged, and anions are negatively charged.
Since there is one Na+ ion in each unit of NaCl, the concentration of Na+ will be the same as the concentration of NaCl. Same with the Cl- ion concentration.
If you had something like 1.0 M CaCl2, it will form Ca2+ ions and 2 Cl- ions. So, the concentration of Cl- ions would be twice the concentration of the Ca+ ions.

cations are + and anions are -
Look at the periodic table. Determine if Na and Cl each will lose or gain electrons.
We see from the formula that there is one mole of Na per NaCl. So Na is also 1M
