Formula mass of ammonia = 14+1×3 = 17

The number of moles in 27.6g ammonia is 27.6÷17= 1.67 mole

A mole is 6.02×10^23 so the number of hydrogen atoms is 1.62 moles of ammonia is 1.62×6.02×10^23×3 = 2.93×10^24

Answer:

The formula mass of ammonia is 14 + 1 3 = 17. The number of moles in 36 g ammonia is 36/ 17 = 2.11mol. A mole is 6.02 10, so the number of hydrogen atoms in a 2.11 moles of ammonia is 2.11 *6.02*10^23 = 1.27 *10^24 atoms .
