what is the total molar concentration of all the ions in .040 M solutions of the following salts in water?

.040 M KCL
.040 M CuSO4
.040 M CaCl2

To find the total molar concentration of all the ions in a solution, we need to consider the dissociation of the salts into their constituent ions.

For the salt KCl, it dissociates into K+ and Cl- ions. Therefore, the total molar concentration of ions in a 0.040 M KCl solution is equal to the sum of the concentrations of K+ and Cl-. Since both ions have a concentration of 0.040 M, the total molar concentration of ions is 0.040 + 0.040 = 0.080 M.

For the salt CuSO4, it dissociates into Cu2+ and SO4 2- ions. Again, we sum the concentrations of the individual ions to find the total molar concentration of ions in the solution. Both Cu2+ and SO4 2- have a concentration of 0.040 M, so the total molar concentration of ions is 0.040 + 0.040 = 0.080 M.

For the salt CaCl2, it dissociates into Ca2+ and 2 Cl- ions. We treat each ion separately and multiply the concentration of Cl- by 2 to account for the two ions formed. The concentration of Ca2+ is 0.040 M, and the concentration of Cl- is 0.040 * 2 = 0.080 M. So, the total molar concentration of ions in a 0.040 M CaCl2 solution is 0.040 + 0.080 = 0.120 M.

Thus, the total molar concentration of ions in the given solutions are:
- KCl: 0.080 M
- CuSO4: 0.080 M
- CaCl2: 0.120 M

I assume this is 3 questions.

KCl gives you 0.04M K and 0.04 M Cl.
CaCl2 gives you 0.04M Ca and 0.08M Cl.
Etc.
