At 20 °C, you will get a saturated solution, and 10 g of $\text{KI}$ will remain undissolved.

#### Explanation:

You know that the solubility of $\text{KI}$ is 50 g/100 g of water.

∴ In 200 g water

$\text{Solubility" = 200 color(red)(cancel(color(black)("g H"_2"O"))) × "50 g KI"/(100 color(red)(cancel(color(black)("g H"_2"O")))) = "100 g KI}$

Since 100 g is the most that you can dissolve, the solution will be saturated.

The extra 10 g will remain undissolved on the bottom of the container.
