Question

13. Number of atoms in 1 ml of ammonia gas at STP is
(1) 2.7 * 1019 (2) 1.08 * 1020
(3) 10.8 x 1020
(4) 5.4 x 1019​

Answer 1

Answer:

option 2

Explanation:

ammonia has 4 atoms

4×6×10^23 atoms

22400ml=4×6×10^23 atoms

1ml=x atoms

x=4×6×10^23/22400

x=0.00108×10^23

x=1.08×10^20 atoms
