Enter your answer in the provided box. 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.

Explanation:

According to ideal gas equation, the product of pressure and volume equals to the product of number of moles, gas constant and temperature.

Mathematically,            PV = nRT

Since, it is given that pressure is constant and Charle's law states that at constant pressure volume of an ideal gas is directly proportional to the absolute temperature.

Therefore,              

                                = constant

So, number of moles will also be constant then. Hence, the formula will be as follows.

                      =

As it is given that is 9.53 L, is 4.36 L, is that is also equal to (215 + 273) K = 488 K.

Now, putting these values into the formula as follows.

                        =

                        =    

                                  = 223.26 K

Temperature in degree celsius will be (223.26 K - 273 K) =  

Thus, we can conclude that temperature (in °C) is needed to reduce the volume to 4.36 L is .
