The nitrate mass in potassium nitrate contributes 62/101 to the total mass. When you weigh out 1 g of potassium nitrate, there is about 0.61 g NO3. To make a 10 ppm solution, you would weigh out 101/62 x 10 mg of potassium nitrate.

Thanks so much and I would add the dry weight to 1 liter of water to get 10ppm?

So. 016 grams in 1 liter water equal 10ppm. If that's accurate I see what you mean about weight
