Question

Find the mass and no. Of amonia(nh3) molecules in it 5.6 l.

Answer 1

Answer:

Given volume :- 5.6L

One mole contain 22.4L

Moles in 5.6L of NH3= 5.6/22.4 =0.25

numbers of molecules =0.25NA

For numbers of atom = multiply the no. of molecule by total no. Atomicity

0.25NA X 4 = NA

Total no. Of atom = NA
