The amount of chemical to make 200 ppm depends on the final volume of the solution. If you had 1 liter, then it would take 200 mg of chemical (0.2 grams). If you had a lake or a pond, it would take a lot more, and you'd need to know the volume of the lake or the pond.

200 kilograms = 440.9 pounds.

200 multiply 120% = 240
A 200 ppm ratio means there are 200 parts of chemical for every one million parts of water. To calculate the quantity of chemical in a certain amount of water, you would need to know the total volume of water. You can then use the ratio to determine the amount of chemical needed.
Well, isn't that just a happy little question! To find the percentage strength of the solution, we need to calculate the amount of chemical in the solution first. Since we have 4kg of chemical in 200 liters of solution, the percentage strength would be 4kg divided by 200 liters, then multiplied by 100 to get the percentage. Happy calculating!
