Going through a basic PPM calculation by volume or by mass will help to cement the concepts you need to understand. For mass, imagine you have 0.98 liters of water with 0.2 g of salt dissolved in it, noting that 1 L of water = 1 kg of mass, so the total mass in the example is ...

Most chemical formulas involve subscripts that are numbers. While these numbers are not followed by units written in the formula, they are, in fact, quantities with units. Thus inherent in chemical formulas is the necessity of conversion factors, which are fractions that convert one unit to anoth...
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. While I appreciate that many authors have statistical and / or ...
Expected Time: How long it’ll take to accomplish the task or activity based on the optimistic, pessimistic and most likely time estimates. The expected time is calculated using the PERT chart formula below. E=(O + (4*M) + P) / 6 Lastly, the PERT chart network diagram allows project ...
Unfortunately, there’s no exact formula for adjusting pH, because factors such as the source of water, growing medium, nutrients, drainage, and growing setup all have an effect on pH. You will need to use trial and error to figure out what amount of pH Up or Down works for you in yo...
(In fact, you can eat it too.) Our ducks love it and one will occasionally figure out how to break through the fencing and ravage the plants. However, mature pickerelweed is pretty hardy and deep rooted, so it can tolerate a few sessions of duck pillaging. Pickerelweed is also ...
To figure out the order lead time, you need to know the following: Actual order lead time (A-OLT) is how long it takes from getting the order to fulfilling it. Requested order lead time (R-OLT) is the time between the order and when the customer wants delivery. ...
Our printables come in aspect ratios that match the most popular standard frame sizes: 2x3, 3x4, 5x7, A (ISO), and 4x5. There is a simple formula for calculating aspect ratios: Aspect Ratio = Width / Height. But we don't want you to worry to much about the math behind it, so ...
The chemical formula of salt is NaCl, and given that the atomic weights of sodium and chlorine are 23 g/mole and 35 g/mole respectively, its molecular weight is 58 g/mole. Divide the molecular weight into the weight of solute in the solution to find the number of moles: 2.7 g ÷ 58...
