For liquids (2% volume/volume): Simply add 2% of the volume to the water. This comes out to 0.06 gallons or 0.96 cups. Note: It is probably more accurate to add 0.06 gallons of whatever to 2.94 gallons of water but honestly errors in measurement will most likely be greater than this small difference. For solids (2% mass/volume): 3 gallons of water are approximately 11.356 liters which is 11356 ml. Since water has a density of roughly 1 g/ml this is equivalent to 11356 g. To make a 2% solution, you would need to add 2% of this weight of whatever you are dissolving which comes out to 0.227 g.

How do you make a 2 percent solution of powder in water?
You stare at it
How many liters of 93 percent acid solution are needed to make a 9 percent solution with 50 liters of water?
4.84
A 280 mL solution is 20 percent salt How much water should be added to make the solution 14 percent salt?
98 mL
How much antifreeze must be added to 12 gallons of 20 percent antifreeze to make a 40 percent antifreeze solution?
4 gallons Let x be the amount of antifreeze needed to be added. We know that the total amount of antifreeze in the new solution must equal the amount of antifreeze in the old solution + x: .40*(x+12)=x+.20*12 .60x=2.40 x=4 gallons
1 gallon solution makes 32 gallons If making 3 gallons how many cups of concentrate is required to make 3 gallons solution?
3/32 gallons = 1.5 cups.
