Question

The Molecular mass of ammonia is 17.
a) How much is the GMM of ammonia?
b) Find out the number of moles of molecules present in 170g of
ammonia
c) Calculate the number of ammonia molecules present in the above
sample of ammonia?​

Answer 1

Answer:

GMM of ammonia are as follows

Explanation:

(NH3) = 14+3×1= 17 = 1GMM

Answer 2

Answer:

a) 17

b) number of molecules = mole × 6. 022 × 10 race to 23 = 10 × 6.022 × 10 race to 23

C) number of mole molecules = mass / GMM = 170 / 17 = 10
