Question

Calculate the number of NH3 molecular in 100grms of NH3

Answer 1

Nitrogen-  1 * 14 = 14
Hydrogen-3 * 1   =  3
                           +
                                14+3=17=Gram molecular mass of Ammonia
mass= 100g
G.A.M=17
No.of moles=mass/G.A.M
                   = 100/17
No.of molecules=No.of moles*avagardo number
                          =100/17 * 6.022*10^22
                             =3.54*10^24
