trying to figure out the formula for this, but when it comes to math..i need it to be told to me in a 3rd grade style lol...
so someone help me out here: how many gallons of hypochlorite (5% available chlorine) have to be added to 100 gallons of water to produce a 120mg/L chlorine solution?
lol somebody heeeeellllp!!!! its probably a basic formula...but i suck at math  |
The internet gave me hypochlorite as 1.11g/cm^3, if 5% is chlorine then you get 0.0555g/cm^3 chlorine or 55,500mg/L. 100gal water is 378.541L.
D1V1 = D2V2
(density required) * (volume of water) = (density of chlorine) * (volume of chlorine)
(120mg/L) * (378.541L) = (55,500mg/L) * X
(120mg/L) * (378.541L) / (55,500mg/L) = X ----- Move the chlorine density over
(120) * (378.541L) / (55,500) = X ----- cancel units
0.818467027L = X ----- Sig figs as appropriate, I was never good at that part though.
Pretty sure that's what you need to do. Bear in mind I'm not a chem person, just a bit of a math/logic person so double check the hypochlorite density and water volume conversion (I know there are different gallons).
