Nitrogen reacts with a metal to form a compound in which there are three atoms of the metal for each atom of nitrogen. if 1.486
g of the metal reacts with 1.000 g of nitrogen, what is the calculated atomic mass of the metal?
use your calculated atomic mass to identify the metal. (for your answer, input the proper chemical symbol for element x.)

Explanation:

1. Write the unbalanced equation

X + N₂ ⟶ X₃N

2. Balance the equation and gather all the data.

MM:               28.01

            6X   +   N₂ ⟶ 2X₃N

m/g    1.486   1.000

3. Calculate the moles of N₂

4. Calculate the moles of X

The molar ratio is 6 mol X: 1 mol N₂

5. Calculate the molar mass of X

6. Identify X.
