Răspuns :
Daca in 3atomi....1 molecula NH3
In 9 atomi....x=>x=9/3=3 molecule amoniac
P.S. Sper sa fie bine..:)

1 mol NH3........6,023 * 10 la 23 molecule.............3 * 6,023 * 10 la 23 atomi H
x moli NH3...................y molecule..........................9 * 6,023 * 10 la 23 atomi H
y = 3 * 6,023 * 10 la 23 molecule
x= 3 moli NH3
x moli NH3...................y molecule..........................9 * 6,023 * 10 la 23 atomi H
y = 3 * 6,023 * 10 la 23 molecule
x= 3 moli NH3
