Options

  1. A6.022 10²²
  2. B2.4088 10²³
  3. C1.8066 10²²
  4. D6.022 10²³

Correct answer

B. 2.4088 10²³

Step-by-step solution

aligned For NH ₃ & 22.4 dm ^3 & =1 ~mol & =6.022 10²² molecules & =6.022 10²² 4 atoms 2.24 dm ^3 & =0.1 ~mol & =0.6022 10²² molecules & =0.6022 10²² 4 atoms & =2.4088 10²³ atoms aligned
