A room of volume of 2 cubic meters is initially at 19 C and 101 kPa. A block of dry ice (solid carbon dioxide) is dropped into the room and then the room is sealed (air tight). After equilibrating, the temperature is 19 C and the pressure is 117.8 kPa. How many kg of dry ice were dropped into the room?
