A 1.30 g sample of dry ice is added to a 745 mL flask containing nitrogen gas at a temperature of 25.0 degrees Celcius and a pressure of 715 mmHg. The dry ice is allowed to sublime (convert from solid to gas) and the mixture is allowed to return to 25.0 degrees Celcius.What is the total pressure in the flask?
