A sample of sulfur hexafluoride gas occupies 9.53 L at 215°C. Assuming that the pressure remains constant, what temperature (in °C) is needed to reduce the volume to 4.36 L? Report your answer to the proper number of significant figures.
Review Charles Law, Boyle’s Law, and Gay-Lussaics Law. Assuming this is an ideal gas, I know that at constant pressure the volume is proportional to to temperature.
