The phrase "a concentration equivalent to" is correct and usable in written English.
It can be used when comparing or equating the concentration of a substance to another measurement or standard.
Example: "The solution has a concentration equivalent to 0.5 mol/L of sodium chloride."
Alternatives: "a concentration comparable to" or "a concentration similar to".
