A home washing machine removes grease and dirt from clothes at a first-order removal rate in which 12% of the grease and dirt is removed per minute of washing. The washing machine holds 50 L of water and has a wash cycle of 5 minutes before discharging the wash water. What is the concentration of dirt and grease in mg/L in the discharge water if the clothes initially contain 0.5 g of dirt and grease? (Hint: removal rate is not k. You must solve for k!)
