Question

number of nitrogen atoms in 2GAM of nitrogen​

Answer 1

Explanation:

Mass of nitogen molecules =42 g

Molar mass of nitogen molecules=42 g

Each nitrogen molecules contain 2 nitrogen atoms.

Moles of nitrogen molecules =Molar massMass=2842=1.5 moles

Number of atoms of nitrogen present in 42 grams of nitrogen gas =2×no. of moles×NA

                                         =2×1.5×6.022×1023=1.8066×1024 atoms

Answer 2

Explanation:

1gm atom of nitrogen=6.02*1023

1gm atom of nitrogen=3.01*123 number of N2 molecules
