If i have a solution of 0.05M iodine in 0.20M KI, what is the concentration iodine in a 10ml solution?

What you wrote can be interpreted in so many ways that I'm not sure exactly what you're asking...

couldnt understand what do u wanna ask??

I think he has potassium tri iodide KI₃ made by 0.05 mol/l I₂ and 0.2 mol/l I^-

I think he has potassium tri iodide KI₃ made by 0.05 mol/l I₂ and 0.2 mol/l I^-

He is asking for the iodine concentration not the iodide!

[shona788]

there's a solution of potassium iodide and in that there is 0.05M iodine.
If i need the molarity of iodine in a 10ml of the solution, can i neglect the concentration of the iodide? or do i need to take it into account?

And if i need to neglect it, then why was the concentration of the KI given? i mean it could have been said...0.05M iodine in KI solution

im a bit lost in all that....

Then the answer is 0.05M. It might as well have been asked, "what is the concentration of iodine in a solution whose iodine concentration is 0.05M? Kind of a stupid problem, if that is really what the question is intended to ask.
