Nitrogen gas (N₂) reacts with a metal to form a compound in which there are three atoms of the metal for each atom of nitrogen. If 1.485 g of the metal reacts with 1.08 g of nitrogen gas to form only this compound, what is the calculated atomic mass of the metal?

Please give your answer with the correct number of significant figures.

Stikstofgas (N₂) reageer met 'n metaal om 'n verbinding te vorm waarin daar drie atome van die metaal vir elke stikstofatoom is. As 1.485 g van die metaal met 1.08 g stikstofgas reageer om slegs dié verbinding te vorm, wat is die berekende atoommassa van die metaal? 

Gee asb jou antwoord met die korrekte aantal beduidende syfers.
