Chlorine is used to disinfect swimming pools and the accepted concentration for disinfection is 1.0 ppm (1 g chlorine per one million grams of water). If a pool with a lenght of 14.0 ft and a width of 16.0 ft requires 1250 mL of a 5.0% slution of clorine by mass to disinfect it, what must the depth of the pool be (in ft)?
