hi..i've done a problem on ppm,but i don't agree with the book result.here is the problem:
I need to make up 2.0 L of a solution whose concentration is 1000 ppm K+. How much potassium chloride must I weigh out to make this solution?My result is 3,81 gr of kcl,while the book result is 3.81 μg of potassium chloride.Who's wrong???thank you for the attention:)
