If the atomic weight of nitrogen is 14.0, what is the mass of one mole of nitrogen gas #N_2#?

Answer 1

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

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"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
