How many gallons of 3 percent salt solution must be mixed with 50 gallons of 7 percent salt solution to obtain a 5 percent salt solution?
50 gallons @ 3% must be added.
If your propane tank was at 40 percent and the propane company filled your tank to 80 percent how many gallons did they put in your tank?
If your propane tank was at 40 percent and the propane company filled it to 80 percent, they added 40 percent of the tank's capacity in propane. The amount of gallons added would depend on the size of the tank, as propane tanks come in various sizes.
How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 60 percent antifreeze?
2 gallons.
How many gallons of gasoline that is eight percent ethanol must be added to two thousand gallons of gas with no ethanol to get a mix that is four percent ethanol?
400 gallons of gasoline with 8% ethanol must be added to the 2000 gallons of gas with no ethanol to achieve a mixture that is 4% ethanol. This is because in the final mixture, the quantity of ethanol is the average of the ethanol content in the two types of gasoline.
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
How much water is added to one can of concentrate?
Typically, one can of concentrate is diluted with three cans of water.
How many gallons of a 80 percent acid solution must be mixed with 60 gallons of a 16 percent solution to obtain a solution that is 60 percent?
Let x be the gallons of the 80% acid solution needed. The amount of acid in the 80% solution is 0.8x, and the amount in the 16% solution is 0.16*60=9.6. We want a total of (x+60) gallons of solution with 60% acid, so we have the equation 0.8x + 9.6 = 0.6(x+60). Solving for x gives x = 24 gallons.
How much water should be added to 1 gallon of pure antifreeze to obtain a solution that is 80 percent antifreeze?
0.25 gallons of water (or 1 quart)
What is 10 percent added to 4.86?
10 percent added to 4.86 is 5.346.
How many gallons of a 50 percent antifreeze solution must be mixed with 90 gallons of 30 percent antifreeze to get a mixture that is 40 percent antifreeze?
Suppose x gallons of 50% antifreeze is added to 90 gallons of 30% antifreeze. Total active ingredient in mixture = 0.5*x + 0.3*90 = 0.5*x + 27 Total volume of mixture = x + 90 gallons Concentration of mixture = (0.5*x + 27)/(x + 90) = (50x + 2700)/(x + 90) percent This should be 40% So 40 = (50x + 2700)/(x + 90) That is, 40x + 3600 = 50x + 2700 so that 900 = 10x and x = 90 So, add 90 gallons of the 50% antifreeze. In fact, for this particular example, there is a short cut. You are adding antifreeze of two concentrations to get a result whose concentration is EXACTLY halfway. This requires the same amount of the two concentrations to be added together.
When NaOH is added to water the hydroxide concentrate increases. What can you conclude about NaOH?
it is a base
How much water should be added to 30 gallons of a solution that is 70 percent antifreeze in order to get a mixture that is 60 percent antifreeze?
First off do not use tap water. Use only distilled water. You will need to add 3 gallons of distilled water to the solution to get 60% antifreeze and 40% distilled water or a 60/40 mix.
