1 pound of wettable powder per 100 gallons equals how many tablespoons per gallon?

1. 0.5 tablespoon

2. 1 tablespoon

3. 2 tablespoons

4. 3 tablespoons

The correct answer is: 1 tablespoon

To determine how many tablespoons of wettable powder are required per gallon when using 1 pound of the powder in 100 gallons of water, we can break down the conversion as follows. First, we need to convert pounds to tablespoons. There are 16 ounces in a pound, and typically, 1 ounce of wettable powder is approximately equivalent to 2 tablespoons. Therefore, 1 pound, which is 16 ounces, would equal: 16 ounces × 2 tablespoons per ounce = 32 tablespoons in 1 pound. Now, if 1 pound of powder is to be diluted in 100 gallons of water, we need to find out how many tablespoons would be needed per gallon. We can calculate the number of tablespoons per gallon by dividing the total amount of tablespoons by the total number of gallons: 32 tablespoons ÷ 100 gallons = 0.32 tablespoons per gallon. To express 0.32 tablespoons per gallon in a more familiar measurement, we convert this into a simpler fraction or approximate value. Knowing that 1 tablespoon is equivalent to 0.5 ounces, we can see that 0.32 tablespoons is indeed just slightly less than 0.5 tablespoons. However, when distributing this evenly across each gallon,
