How many gallons of 25 percent emulsifiable concentrate would you add to a 50 gallon tank to achieve a 1 percent active ingredient mixture?

To determine how many gallons of a 25 percent emulsifiable concentrate are needed to achieve a 1 percent active ingredient mixture in a 50-gallon tank, we must first calculate the total amount of active ingredient required in that tank.

The total volume of the mixture is 50 gallons, and the target concentration for the active ingredient is 1 percent. Therefore, the total amount of active ingredient needed in the tank can be calculated as follows:

1 percent of 50 gallons = 0.01 × 50 = 0.5 gallons of active ingredient.

Next, since the emulsifiable concentrate is 25 percent active ingredient, it means that in every gallon of this concentrate, there are 0.25 gallons of active ingredient. To find out how many gallons of the concentrate are required to achieve 0.5 gallons of active ingredient, the calculation is:

Required gallons of concentrate = Total active ingredient required / Concentration of active ingredient in the concentrate

= 0.5 gallons / 0.25 = 2 gallons.

This calculation would indicate that 2 gallons of the 25 percent emulsifiable concentrate are necessary to achieve the desired active ingredient concentration in the 50-gallon tank. However, as 2.075 gallons
