Question

how many atoms are present in 1ml of NH3 at STP​

Answer 1

Answer:4 atoms

Explanation:

So 1 ml has 1/22400 moles at STP.1 mole = 6.022 x 1023 molecules. So number of molecules of ammonia in 1 ml = 6.022 x 1023/22400. Now, multiply this number by 4 to get the total number of atoms as each molecule of ammonia has 4 atoms ( 1 N and 3 H)

Answer 2

1/22400*6*10^23

2.67*10^19 molecules of NH3 are present

Hope it helps
