Let's assume you have 1 L of the 37% solution by volume of chemical A. So your solution would contain 0.37 L of A & 0.63 L of water.
0.37 L of A / (0.37 L of A + 0.63 L of water) = 37% solution of A
Obviously in order to dilute the solution to 2% we have to add water. Now we need to figure out how much. We'll call it X. So you set up the ratio as follows & solve for X.
0.37 / (0.37 + 0.36 + X ) = 0.02
0.37 = 0.02 (1.00 + X)
0.37 = 0.02 + 0.02X
0.37 - 0.02 = 0.02 + 0.02X - 0.02
0.35 = 0.02X
0.35/0.02 = X
X = 17.5, so you would have to add 17.5 L of water to the originial 37% solution to dilute it to 2%.
Obviously this answer will change depending on how much of the 37% solution you have to start with but the procedure to figure it out is still the same.

A. 16 of 18 percent and 2 of 9 percent b. 14 of 18 percent and 4 of 9 percent c. 16 of 9 percent and 2 of 18 percent d. 14 of 9 percent and 4 of 18 percent
37 percent of 200 is what number?
74 37% of 100 = 37 200 = 2 * 100 (37% of 200) = 2 * (37% of 100) Again, 37% of 100 = 37 37 * 2 = 74
What is 37 1 over 2 percent to a decimal?
0.37537 1/2%= 37 + (1 ÷ 2)%= 37 %+ 0.5%= 37.5%/100%= 0.375 in decimal

How much water must be added to 40ml of a 25 percent by weight solution to make a 2 percent by weight solution?
To make a 2% solution from a 25% solution, you need to dilute it. Let x ml be the amount of water needed. Using the equation for mass balance: 0.25(40) = 0.02(40 + x), solve for x to find that x = 875 ml of water needs to be added.
How many liters of 9 percent salt solution and 18 percent salt solution are needed to make 18 liters of 10 percent salt solution?
A. 16 of 18 percent and 2 of 9 percent b. 14 of 18 percent and 4 of 9 percent c. 16 of 9 percent and 2 of 18 percent d. 14 of 9 percent and 4 of 18 percent
37 percent of 200 is what number?
74 37% of 100 = 37 200 = 2 * 100 (37% of 200) = 2 * (37% of 100) Again, 37% of 100 = 37 37 * 2 = 74
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.
How many litres of 12 percent sodium hypochlorite solution are needed to make 100 Litre of 2 percent sodium hypochlorite solution?
To make a 2% sodium hypochlorite solution from a 12% solution, you can set up the equation: 12% solution * x litres = 2% solution * 100 litres Solving for x, you get: x = (2% solution * 100 litres) / 12% = 16.67 litres Therefore, you would need 16.67 litres of the 12% sodium hypochlorite solution to make 100 litres of a 2% solution.
What color is 2 percent bromine solution?
2 percent bromine solution typically has a reddish-brown color.
37 out of 50 is equivalent to what percent?
It's 74%. The easiest way to convert a fraction to a percent is to make the denominator 100, because then the numerator will be your percent. So to make 37/50 have a denominator of 100, you have to multiply both numbers by 2 (because 50*2 is 100). That gives you a new fraction of 74/100, so 74% is your percentage.
What is 37 1 over 2 percent to a decimal?
0.37537 1/2%= 37 + (1 ÷ 2)%= 37 %+ 0.5%= 37.5%/100%= 0.375 in decimal
How do you make 3 percent strength solution with 37 percent strength of H2O2?
To make a 3% hydrogen peroxide solution from a 37% solution, you can dilute the 37% solution with distilled water. The general formula for dilution is: C1V1 = C2V2, where C1 is the initial concentration, V1 is the volume of the initial solution, C2 is the final concentration, and V2 is the final volume of the solution you want to make. In this case, you can calculate the volume of the 37% solution and the volume of distilled water needed to achieve a 3% solution.
