#4.59 * 10^23# particles

Explanation:

Find the molar mass of NH3 on the periodic table (it's 17.031 grams.) Divide the quantity given by this number to find the number of moles. Multiply by the number of moles by Avogadro's number #(6.023 * 10^23)# to find your answer.

#13.0g * (1 mol)/(17.031g) * (6.023 * 10^23)/(1 mol) = 4.59 *10^23 # particles

Finally think about the answer. You're looking for the amount of particles (tiny things.) In 13 grams of material, you can expect there to be an insanely huge amount of particles. Is the answer a huge number?
