Question

2. Arrange the followings in the order of increasing number of molecules. a) 34g NH3 b) 10g H2 c) 1 mole carbon ​

Answer 1

Answer:

b) 10g H2

Explanation:

this is the correct answer

Answer 2

Answer:

1 mole of Carbon, 34g of NH3 , 10g of H2

(Order from lowest number of molecules to Highest number of molecules)

Explanation:

GMM of  NH3 = 17g

GMM of H2 = 2g

GMM of C = 12g

a) 1 mole of NH3 = 17g

   ? moles of NH3 = 34g

= 34/17 = 2 moles of NH3 molecules

b)1 mole of H2 = 2g

   ? mole of H2 = 10g

= 10/2 = 2 moles of H2

c)1 mole of Carbon
