Determine what mass of Potassium Iodide should be dissolved in 200 g of water to make a 3.0 percent solution?

3% = 3 g solute / 100 g water
So, for 200 g water, you will need 2X3 g = 6 grams potassium iodide
This assumes that what's meant is "weight percent", sometimes abbreviated as "w/w %" or "wt %".
It would be highly unusual for a chemist to specify the concentration as a percent.

What is the difference between a percent saturated solution of ammonium sulfate and percent wv solution of ammonium sulfate?
Bioc 4025? Just a guess. Definition of % Saturation: The amount of a substance that is dissolved in a solution compared to the amount that could be dissolved in it. % w/v Solution: This is in terms of weight (g) per volume (mL). 2% for example is 2 g per 100 mL. gl
How do you make 5 percent potassium hydroxide solution?
A solution that is refered to as a percentage of something (like potassium hydroxide, KOH) refers to the mass of the solute compared to the total solution, so a 5% KOH solution would be 5g KOH + 95g H2O, and the 5g KOH would be 5% of the 100g total of the solution.
