Answer:

28g/mol

2 moles of nitrogen are present

Explanation:

The molar mass is defined as the mass of a chemical when 1 mole of this substance is present and is used to convert mass of the substance to moles or vice versa. Is widely used in stoichiometry problems.

1 atom of nitrogen has a molar mass of 14g/mol. N₂(g) -The molecule that contains 2 atoms of nitrogen- has a molar mass of 28g. That is 28g/mol.

56g of N₂ are:

56g * (1mol / 28g) =

2 moles of nitrogen are present
