Question

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"`.

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"`
