Sodium carbonate is often added to laundry detergents to soften hard water and make the detergent more effective. Suppose that a particular detergent mixture is designed to soften hard water that is 3.8Γ10β3M in Ca2+ and 1.1Γ10β3M in Mg2+ and that the average capacity of a washing machine is 22.0 gallons of water. 1gallon=3.785L If the detergent requires using 0.70 kg detergent per load of laundry, determine what percentage (by mass) of the detergent should be sodium carbonate in order to completely precipitate all of the calcium and magnesium ions in an average load of laundry water.
