Calculate the density, in grams per liter, of a gas at STP if 3.16 L of the gas at 28.5 °C and 734.2 mmHg weighs 0.269 g.

Solutions

Expert Solution

given conditions                                 STP conditions

P1 = 734.2mmHg                              P2 = 760mmHg

V1   = 3.16L                                     V2   =

T1   = 28.50C   = 28.5 + 273 = 301.5K              T2   = 273K

        P1V1/T1     = P2V2/T2

          V2           = P1V1T2/T1P2

                          = 734.2*3.16*273/301.5*760   = 2.76L

density   = mass/volume

               = 0.269/2.76   = 0.097g/L >>>>>answer
