how many molecules of ammonia are present in 34 g of ammonia (formula = nh3)?
203407
therefore 34 g of NH₃ contains 12.044*10²³ molecules .
1411419
Ammonium nitrate has the chemical formula NH4NO3, which contains two nitrogen (N) atoms, four hydrogen (H) atoms, and three oxygen (O) atoms. In this formula, the ammonium (NH4+) ion and nitrate (NO3-) ion are bonded together by an ionic bond. Ammonium nitrate has various uses in various industries.

Answer and Explanation: The atomic mass of ammonia (or NH3) is 17.03.
587666
A lot. 9.34g divided by 18g/mol (the molar mass of water) gets you about 0.52 moles, times Avogadro's number of 6.02x1023 = 3.13x1023 molecules.

Ammonia, NH3, is a chemical compound composed of one nitrogen atom and three hydrogen atoms.
622148
The number of molecules in a single mole of any compound is given by Avoadro's constant, which is 6.023x10^23. There would be 6.023x10^23 molecules of ammonia in 17 grams of the substance.
