A balloon at30.0C has a volume of 222 mL. If the temperature is increased to 53.1C and the pressure remains constant, what will the new volume be, in mL?

According to Dalton, the pressure exerted by a gas inside a container is proportional to the number of molecules of that gas.  If 4.00 x 1023 molecules of N2 and 2.00 x 1023 molecules of O2 are mixed in a container they exert a total pressure of 1686 torr.  What portion of that pressure (in torr units) is exerted by the N2?  Report answer to four significant figures in decimal notation. _____________________ torr,   What portion of that pressure (in torr units) is exerted by the O2?  Report answer to four significant figures in decimal notation. ____________________ torr
