Calculate the final Celcius Temperature when 125 mL of chlorine gas at 25 degrees Celsius  is heated to give a volume of 175 mL.

A sample of polyatomic gas weighs 6.94 g and at a temperature 30.0 C it has a volume of 2.49 L and a pressure of 361 torr.   What is the molecular weight of the gas? (hint: remember that PV=nRTPV=nRT) The molecular structure of the gas in the above problem has a total of 7 atoms and contains only sulfur and fluorine atoms. Based on its molecular weight you calculated above, which of the following empirical formulas is most likely to be correct for the gas? SF6 S2F5 S3F4 S4F3 S5F2 S6F None of these formulas are correct
