A home washing machine removes grease and dirt from clothes in a first-order process in which 12% of the grease on the clothes is removed per minute. The washing machine holds 50.0L of water and has a wash cycle of 5.00 minutes before discharging the wash water. What will be the grease concentration (in mg/L) in the discharge if the clothes initially contain .500g grease?
