What is the molarity of a solution composed of 4.27 g of potassium iodide (KI) dissolved in
enough water to make 0.304 L of solution?
Answer in units of M.

0.0845 M

Explanation:

First we convert 4.27 grams of potassium iodide into moles, using its molar mass:

Now we calculate the molarity of the solution, using the number of moles and the given volume:

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

i believe the answer is true.
