Enter vour answer in scientific notation Chlorine is used to disinfect swimming pools. The accepted concentration for this purpose is 1 ppm chlorine or l g of chlorine per million g of water. Calculate the volume of a chlorine solution (in milliliters) a homeowner should add to her swimming pool to achieve 1.00 ppm chlorine if the solution contains 6.00 percent chlorine by mass and there are 3.85 x 101 gallons of water in the pool.

Under certain water conditions, the free chlorine (hypochlorous acid, HOCI) in a swimming pool decomposes according to the law of uninhibited decay. After shocking a pool, the pool boy, Geoff, tested the water and found the amount of free chlorine to be 2.8 parts per million (ppm). Twenty-four hours later, Geoff tested the water again and found the amount of free chlorine to be 2.4 ppm. What will be the reading after 2 days (that is, 48 hours)? When...
