Respuesta :

The molar mass of an ideal gas which has a density of 1.4 g/L measured at 25°C and 0.60 atm is 31.4 g/mol.

Using the ideal gas equation,

             PV = nRT

where,

P = pressure of the gas

V = the volume it occupies

n = the number of moles of gas

R = the universal gas constant = 0.0821

T = absolute temperature of gas

         Molar mass =      given mass                                                   ------ 1

                                  number of moles

          Density =  mass                                                                         ------2

                           volume  

          PV =  m   . RT

                   Mm

By rearranging, we get-

         Mm = ρ . RT

                         P

         Molar mass = 1.4 x 0.0821 x (273.15 + 25)

                                               0.60

          Molar mass = 31.4 g
