Question

2 mole of N2 is reacted with 4 moles of H2 to produce ammonia . Mass of ammonia produced is.​

Answer 1

answer:

45.39 grams of ammonia is produced.

Explanation :

N₂ + 3H₂ → 2NH3

From the balanced equation, we can understand that 1 mole of N₂ combines with 3 moles of H₂, to form ammonia gas.

So, 2 moles of N₂ will combine with : = 6 moles of H₂

= (2 x 3)

But here we are given only 4 moles of H₂. Thus, H₂ is the limiting reagent and will control the amount of product.

Now, again from the balanced equation :

:: 3 moles of H₂ → 2 moles of NH3

.. 4 moles of H₂ →2.67 moles of NH3

Mass of ammonia formed :

= Number of moles x Molar mass

= 2.67 x 17

= 45.39 g
