Question

no. of atoms in 4.25g of NH3​

Answer 1

Answer:

1.5*10^23

Explanation:

avagadro no*given compound (GM)/ molecular weight

6.022*10^23*4.25/17=1.5*10^23

Answer 2

17gm NH3=NA molecules ....

4.25g=(NA/17)*4.25 molecules...

Number of atoms = 4*(NA/17)*4.25 atoms..

Thus the answer will be ....

NA atoms i.e. 6.022*10^23
