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. Nā(g) -The molecule that contains 2 atoms of nitrogen- has a molar mass of 28g. That is 28g/mol.
56g of Nā are:
56g * (1mol / 28g) =
2 moles of nitrogen are present
