Divide the mass of the solute by the mass of the solution using a calculator. For dilute solutions, this will result in a small number. Continuing the previous example, 0.005 / 1000 = 0.000005. Calculate the concentration in ppb by multiplying the ratio of the mass of solute to mass of s...
Once you have your ppm, you can make proper adjustments to get it in the desirable range. Speaking of which, you’re going to need to know what ppm range you want for your water. This can vary depending on which nutrients you use, but here are some good guidelines: Tap water:400ppm ...

Indicate how much solute and solvent is needed to make 500.0 mL of a 5.68% (w/w) H2S solution in water. How much dry solute would you need to prepare 135 mL of a 0.545 M KCl solution? Describe how to prepare 100.0 mL of a solution containing 15.0 ppm Na+...
Steve, in Seattle writes: I began this project out of both frustration and a specific curiosity. I have, over the years, studied many excellent articles at WUWT. The articles that are mathematical / graphic “ heavy “ are of particular interest to me. W
Water plantswith pH’ed nutrient solution or add water to a hydroponic reservoir Check– Soil or soilless growers who hand water their plants should check the pH of their runoff water to make sure it’s in the right range – try to test the earliest runoff if possible. Hydroponic growers ...
Determine the total volume of the solution and convert it to liters. The most common conversion would be milliliters (mL) to liters (L). Perform this conversion by dividing the total milliliters by 1,000. 500 ml of solution would be converted to 0.5 L of solution (500 / 1000 = 0.5...
(<1000 ppm as per the jedec standard) in the plating/finish. q. does vishay intend to eliminate lead in other areas of the components? a. yes, vishay is in the process of eliminating lead in other parts of the component. for some technologies there currently is no technical solution to...
The kilogram has an extended set of gram-like units, which are related to it by various powers of 10. Therefore it is simple to convert from one gram-like unit to a different one. Answer and Explanation: 1 The petagram and milligram are both extended units from the base kilogram u...
These parasites can easily transfer from tank to tank via fish, plants, decorations, or equipment. In this guide, I’ll explain what Ich is, how it infects your aquarium, how to identify its symptoms, and most importantly, how to treat it. With the right knowledge and action, you can ...
