The ratio is "one to 99", or "one part per hundred", regardless of the size of the sample.
If you only want to prepare one gallon of mixture, you add (1% of one gallon) of chemical
to (99% of 1 gallon) of water.
1 gallon = 128 fluid ounces
Chemical = 0.01 x 128 = 1.28 fluid ounce
Water = 0.99 x 128 = 126.72 fluid ounces
Together, you have (1.28 + 126.72) = 128 fluid ounces = 1 gallon.
Call the unknown amount of substance R to be added a. The mixture initially contains 1 gallon of S combined with 2 gallons of R. After the addition, the mixture will contain the oiginal 1 gallon of S and (2 + a) gallons of R. In order for the content of S to be 25 % after the mixing, 1 gallon must equal 0.25(1 + 2 + a)gallons, or (1 - 0.75)gallons = (0.25)a, or a = 0.25/0.25 = 1 gallon.
To calculate the amount of chemical needed per gallon, first determine the total amount of chemical in the 5 gallons of water. Since 16 ounces in 5 gallons equal 500 ppm, you can set up a proportion: (16 ounces/5 gallons) = (x ounces/1 gallon). Solve for x to find out how many ounces of chemical are needed per gallon.
Oh, what a lovely question! A mega gallon is a million gallons, which is quite a lot of paint for our happy little trees. Just imagine all the beautiful landscapes we could create with that much paint!
21 ounces to 100 gallons of water means (21/100) = 0.21 ounce per gallon of water.The proper amount of chemical is only 0.16% of the amount of water it goes into. It's hard to get the correct concentration for small batches.This is probably why they give you the instructions in terms of 100 gallons ... it would be tough to measure 0.21 ounces accurately.
Well, isn't that just a happy little question? You see, there are 8 pints in a gallon, so if you have 24 pints, that would be 3 gallons. Just imagine those gallons of paint ready to create a beautiful masterpiece on your canvas.

GALLONS As in: 1 gallon, 2 gallons.
There are two half gallons in a gallon.
a gas and oil mixture of 50 gallons of gas per gallon of 50:1 injection oil
Fill the 5 gallon jug Pour from the 5 gallon to fill the 3 gallon jug You now have 2 gallons in the 5 gallon jug Empty the 3 gallon jug Pour the 2 gallons from the 5 gallon jug into the 3 gallon jug Fill the 5 gallon jug Pour from the 5 gallon jug to fill the three gallon jug -- this will tale 1 gallon You now have 4 gallons in the 5 gallon jug
fill the 7 gallon bucket, dump it into the 5 gallon bucket and save the remaining 2 gallons, repeat and you have 4 gallons.
