The Atomic Mass of 35.45 is an average value. Chlorine has two principal stable isotopes, 35Cl (75.78%) and 37Cl (24.22%). Thus we account for the proportion of each isotope and derive an average atomic mass for chlorine.

Atomic mass = 0.7578(35) + 0.2422(37) = 35.45

What is chlorines mass number?

Chlorine's mass number is 35.5. This is an average value due to the presence of two isotopes of chlorine, chlorine-35 and chlorine-37, in nature.


What is free chlorine in a pool?

Free Chlorine is the Chlorine which is free to do its work in the pool, as opposed to Combined Chlorine which is chlorine that has combined with contaminants and is tied up and ineffective as a sanitizer in the pool. Sometimes you will see it abbreviated as FAC, which stands for Free Available Chlorine.


What do you do when your total chlorine is high and your free chlorine is low?

Total Chlorine = Free Chlorine + Combined Chlorineor, put another wayTotal Chlorine - Free Chlorine = Combined ChlorineFree Chlorine is the chlorine that is doing its job.Combined Chlorine is the chlorine that has combined with contaminants such as nitrogen. It is ineffective as a sanitizer and it is noxious.Total Chlorine is the total of these two levels.To eliminate the Combined Chlorine (making all the chlorine in the pool Free Chlorine) you must shock the pool to remove the contaminants. You must reach "Breakpoint Chlorination", which is the addition of chlorine to your pool equivalent to the Combined Chlorine level times 10.example:Total Chlorine = 1.5ppmFree Chlorine = 1.0ppmSo, the Combined Chlorine (the difference between the two tests) is .5ppmBreakpoint chlorination, in this example would be .5ppm X 10 = 5ppm. So, in this example, you would add enough chlorine to your pool to raise the chlorine level up by 5 parts per million.


What is the name of the covalent compound ClF3?

ClF5 Is the formula for Chlorine pentaflouride.


How do you get high free chlorine to match total chlorine?
