Question

4) Calculate the mass of

(b) 0.05 mole of Ammonia.​

Answer 1

molar mass of ammonia = NH3 = 14 +3×1 = 17g

mass of its 0.05 moles = 17 ×0.05 = 0.85g

Answer 2

Answer:

Ans= 0.85 gram

Explanation:

Ammonia= NH3

Mass of Nitrogen(N) = 14

Mass of Hydrogen (H)= 1

" " H3 = 3

: Mass Of 1 mole of NH3 =

Mass of N + Mass Of H3

14+1×3 = 17 gram

Mass of 1 mole of NH3 =17 gram

Mass of 0.05 mole of NH3

= 0.05× Mass of NH3

0.05×17=0.85 gram
