To calculate the volume of chlorine solution needed to achieve 1 ppm in a pool containing \( 4.64 \times 10^{4} \) gallons of water, we start by finding the total mass of the water. 1 gallon of water weighs approximately 3,785 grams. Therefore, the mass of water in the pool is: \[ 4.64 \times 10^{4} \text{ gallons} \times 3,785 \text{ g/gallon} = 1.754 \times 10^{8} \text{ g} \] To achieve a concentration of 1 ppm, the mass of chlorine required is: \[ 1 \text{ ppm} = \frac{1 \text{ g chlorine}}{1 \text{ million g water}} \times 1.754 \times 10^{8} \text{ g water} = 0.1754 \text{ g chlorine} \] Next, we need to determine how much of the 6.00% chlorine solution is needed to provide 0.1754 g of chlorine. Since the solution is 6.00% chlorine by mass, we can say: \[ 0.06 \times m = 0.1754 \text{ g} \quad \Rightarrow \quad m = \frac{0.1754 \text{ g}}{0.06} \approx 2.9233 \text{ g} \] Since the density of the chlorine solution is \( 1.00 \text{ g/mL} \), this mass translates directly to volume in mL: \[ V = 2.9233 \text{ mL} \] Rounding this to three significant figures gives us: \[ \approx 2.92 \text{ mL} \] Inputting this into the required format: 2.92 mL. 2.92 × 10^0
