Question

5.1g of ammonia by calculate the number of moles

Answer 1

Wt of NH3 given=5.1
NH3's molecular mass=14+1*3=17
As
No.of moles= wt of NH3 given/molecular mass
So 5.1/17
=0.3 moles

Answer 2

Answer:

Atomic mass of ammonia=17u

Molar mass of ammonia=17g

Thus,the number of mole=

Given mass/Molar mass

5.1/17=0.3

Explanation:

Atomic mass of ammonia=17u

Molar mass of ammonia=17g

Thus,the number of mole=

Given mass/Molar mass

5.1/17=0.3
