Answer:

The mass of one mole (molar mass) of nitrogen gas #("N"_2")# is #"28.0 g/mol"#.

Explanation:

The molar mass of an element is its relative atomic mass (atomic weight) on the periodic table in g/mol. The molar mass of the element nitrogen is #"14.0 g/mol"#. In order to determine the molar mass of nitrogen gas #("N"_2")#, multiply the molar mass of the element nitrogen times two.

Molar mass of nitrogen gas #("N"_2")##=14.0"g/mol"xx2##=##28.0"g/mol"#
