concentration*amount + concentration*amount = concentration*amount
.8x + 0.0*4L = .2(x+4L), solve for x

.8x= .2x+.16
x =.2666 L
266ml per 4L


*messed up, see real answers below

solution 1 + solution 2 = solution 1+2.  Just put in the known variables, and solve for the unknown.

Lets pretend 100mls water  = 100% 
now you want a 2% solution
You have you 100% solution which is 100mls
Now you just remove 2mls water and add 2mls of whatever you want
And it will now be 2% and so on and on
If you want 20% take out 20mls and add 20mls of whatever, so your solution will now be 100% solution but have 20% whatever.
That can work for anything like powders or whatever you like
You can also add this ontop of your 100mls 100%  so you will end up having 120mls or whatever

It is that easy! Your just not getting it and dont understand simple math. So im leaving it as that.

80% is 100% put 1.6mls ha in your solution and its 2%

To make it exact, subtract 1.6mls out of solution a.

Yeah, sorry was pretty stoned last night.  If it was a liquid it would be taking out about 2.5 mls and adding 2.5 mls of the solution to bring it to 2%


I'm trying to figure this powder thing out now.

And this is per liter, not gallon that I'm doing all this in.  Makes life a lot easier.

So take 1000mls water, add 1250mls of your humic acid solution, this will give you a 100mg/ml solution. We'll call this solution A

Take you 1000mls of water, take 250 of that out, then add 250mls of solution A.  This will achieve a roughly 20% solution.

yo guys, I actually used a math book, just do a little bit of algebra and it will be done for you. I also wrote down the wrong numbers because I was looking at the wrong part of the paper. I multiplied .2*4=0.16

"So take 1000mls water, add 1250mls of your humic acid solution"

your looking at a 44.4% solution that way. yours is more like if you had 4L.

Here I use 1 gallon = 3.76L

Solution = Concentration * Amount
    Where Concentration is a %, between 0 and 1. 80% = .80
    Amount = Volume of liquid

Solution 1 + Solution 2 =  Solution 3


Solution 1 = 0.80 * X (Amount unknown)
Solution 2 = 0.00 * 3.76L Amount (Water) = 0
Solution 3 = (Desired Concentration) * Amount(1+2)

Solution 1 + Solution 2 =  Solution 3
0.80*X + 0.0*3.76 = 0.20 * (X + 3.76)L
Simplify (remove 0's, distribute 0.20 on right)
0.80x = 0.20x + 0.752L

put all the unknowns on one side, everything else on the other... subtract 0.20x from both sides
0.60x = 0.752L

Solve for x by dividing both sides by 0.60

X = 1.253L per 3.76L (1 gallon)

So if you know what your doing, tell him his answer then.  Cause what I put down makes sense to me.

    #650498 - 12/10/12 08:01 PM (4 years, 9 months ago)

Probably a more important calculation is: Make 1 gallon of 20% HA solution from an 80% Solution. Like if you had a gallon jug and just wanted to top it off, not make 5.25L of it.

Same thing, just need to substitute another variable and solve it in terms of the other.

X = Amount HA solution, Y = Amount Water. ( in liters)
1Gal = 3.76L

0.80*X + 0.00*Y = 0.20(X+Y)
and we know that X + Y = 3.76L
Solve in terms of Y (subtract X from both sides)
Y = 3.76 - X
Substitute in 3.76 - X for Y, Which brings the equation to
0.80*X + 0.00*(3.76 - X) = 0.20(X + 3.76 - X)
0.80X = 0.20(3.76)
0.80X = .752
Divide both sides by 0.80 and
X = .940 Liters, or 940mL of HA Solution to make 1 Gallon @ 20%


*hawk, your logic has him mix two times. If I'm cutting a 10" board to 6", I don't cut it at 8" first, then again at 6 :wink:

Mine did get the right solution thought right?  I just wanna make sure that my logic is correct.

I just went through the first mixing--it makes 44%, What is the final volume of 20% solution?

    #650506 - 12/10/12 08:25 PM (4 years, 9 months ago)

Solution A:
0.80(1250mL) + 0.00*(1000mL) = X*(2250mL)
X = 0.44444

Solution A = 44% HA

so
if C= the final concentration,

0.44(250mL) + 0.00(750mL) = C(1000mL)
concentration = 11%.

you somehow magically come up with mg's in your equation " a 100mg/ml solution", but mass is never considered
