52.0 divided by 65 g/mol gives you 0.8mol

Answer:

0.800 moles

Explanation:

  • n = [tex]\frac{m}{M}[/tex]
  • n = moles , m = mass in grams (g) , M = molar mass (g/mol)
  • Molar mass is the sum of atomic masses in the compound

           Na = 22.99 g/mol

           N = 14.01 g/mol x 3 = 42.03 g/mol

  • n = [tex]\frac{52}{22.99+42.03}[/tex]
  • n = 0.799 = 0.8 moles
