What is the molarity of 495 mL solution containing 21.1 g of potassium iodide?

We have 495 ml, but we need to convert this to 1000, so we divide by 495 and multiply by 1000. We also do this to 21.1g. 21.1/495*100 is 42.626g. KI's molecular weight is 166g/mol. 42.626/166 is 0.2568 molar.

What is difference between SSKI and Lugol's Solution?
It's the same thing. It is a solution of water that has been saturated to the max with potassium, then iodide is added (a form of iodine). So it is a potassium iodide solution.
What is the molarity of a solution prepared by dissolving 2.41 g of potassium iodide KI in 100 mL of water?
Find moles potassium iodide first.2.41 grams KI (1 mole KI/166 grams) = 0.01452 moles KIMolarity = moles of solute/Liters of solution ( 100 ml = 0.1 Liters )Molarity = 0.01452 moles KI/0.1 Liters= 0.145 M KI solution================

What is observed when a solution of potassium iodide is added to silver nitrate solution?
A yellow precipitate of silver iodide (AgI).
How does ferric chloride reacts with potassium iodide solution?
In aqueous solution they would not react. They would form a solution of ferric ions, chloride ions, potassium ions, and iodide ions.
What happens when silver nitrate solution is added to potassium iodide solution?
Ag(NO3)(aq) + KI(aq) ---> K(NO3)(aq) + AgI(s)
What happens when a solution of potassium iodide is added to a solution of lead nitrate taken in a test tube?
Lead iodide (Pb2I) precipitates as a yellow solid, leaving a solution of potassium and nitrate ions.
