This depends on the volume of the 40 percent solution you have. The question can be rewritten as:
40%a/(a+b) = 3% where a is the volume of the 40% solution, and b is the volume of water we need to add. Multiply both sides by (a+b) to get:
40%a = 3%a + 3%b
Subtract 3%a from both sides to get
37%a = 3%b
Divide by 3% to get:
12.3333...a = b
Thus whatever the current volume is, you need to add 12.33333 times that volume in water in order to get a 3% solution.

What is 40 increased by 3 percent?
40 increased by 3 percent = 41.2 = 40 + (3% * 40) = 40 + (0.03 * 40) = 40 + 1.2 = 41.2
What number is 3 percent of 40?
3% of 40 = 0.03 x 40 = 1.2
What is two-thirds and one third intravenous solution?
2.3 percent glucose solution and .3 percent sodium solution
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.
What is 40 percent off of 5 dollars?
3 dollars, because 40 percent of 5.00 is 2.00, and subtracting that from 5 is simply 3.
What percentage is 3 percent of 40?
3 percent of 40 = 1.23% of 40= 3% * 40= 0.03 * 40= 1.2
What is 40 increased by 3 percent?
40 increased by 3 percent = 41.2 = 40 + (3% * 40) = 40 + (0.03 * 40) = 40 + 1.2 = 41.2
Percents are often used to show the strength of solutions Which solution is stronger the 2 percent or the 3 percent?
A 3 percent solution is 1.5 times as strong as a 2 percent solution.
What is 3 over 40 as a percent?
3 over 40 as a percent = 7.5%= 3/40 * 100%= 0.075 * 100%= 7.5%
How many liters of 50 percent alcohol solution and 20 percent alcohol solution must be mixed to obtain 3 liters of 40 percent alcohol solution?
Let there be x litres of 50% solution and y% of 20 % solution, then you have two equations by considering the amount of alcohol and the total amount of liquid:50% x + 20% y = 40% of 3 litresx + y = 3 litresThese are two simultaneous equations involving 2 unknowns which can be solved:Double {1} and subtract from {2} to give:x - x + y - 40%y = 3 - 80% of 3→ 60% y = 20% of 3→ y = 20%/60% of 3 = 1/3 of 3 = 1Substitute for y in {2} to get:x + 1 = 3x = 2Therefore you need 2 litres of 50% solution and 1 litre of 20% solution.
What is 3 over 40 in a percent?
Expressed as a percentage, 3/40 x 100 = 7.5 percent.
How do you make 10vol peroxide with 40 vol peroxide?
To make a 10 vol peroxide solution from a 40 vol peroxide solution, you would need to dilute the 40 vol peroxide solution by adding three parts water for every part of the 40 vol peroxide solution. For example, mix 1 part 40 vol peroxide with 3 parts water to achieve a 10 vol peroxide solution.
