Ga sealed container holds 0.020 moles of nitrogen (n2) gas, at a pressure of 1.5 atmospheres and a temperature of 290 k. the atomic mass of nitrogen is 14.0 g/mol. the boltzmann constant is 1.38 × 10-23 j/k and the ideal gas constant is r = 8.314 j/ mol · k = 0.0821 l · atm/mol · k. the mass density of the gas is closest to

Explanation:

The given data is as follows.

        n = 0.020 moles,    P = 1.5 atm

        T = 290 K,      molar mass of nitrogen = 14.0 g/mol

         R = 8.314 J/mol,         d = ?

It is known that  the relation between density, pressure, and temperature is as follows.

                 P =

Putting the given values into the above relation and calculate the density as follows.

              P =

             1.5 atm =

                    d =

                      = g

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