What is the density (in g/l) of a gas with a molar mass of 70.49g/mol at 0.874atm and 389k?

Explanation:

According to the ideal gas law, PV = nRT

where, n = number of moles

Also, density =

Since,   n =

Therefore, ideal gas equation can also be written as follows.

                  PV = nRT

                  PV =

          = dRT

Hence, putting the given values into the above formula as follows.

                      6.161 atm g/mol =

                             d = 0.193 g/L

Thus, we can conclude that density of the given gas is 0.193 g/L.

the answer is 1260
