What is the total number of moles present in a 52.0 gram sample of nan3?

0.800 moles

Explanation:

n = 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 = n = 0.799 = 0.8 moles
