617.647 Kg hydrogen will be required when gaseous nitrogen and gaseous hydrogen are reacted at high temperatures in the presence of a catalyst, ammonia (and no other product) is formed. if a chemical plant has to synthesize 350 kg of ammonia, is 617.647 Kg by using unitary method to calculate the moles
the mass can be calculate as follow:
first we should calculate the moles of ammonia
The chemical formulas for the reaction of hidrogen and nitrogen are:
[tex]N_2+3H_2 = > 2NH_2[/tex]
We need to calculate the moles of ammonia
n = mass/ molecular weight
n NH3 =350000/17
n NH3 =
then we can calculate the moles of hydrogen
unitary method is used to calculate the moles of hydrogen
[tex]n H_2 = \frac{3}{2} X n NH_3\\n H_2 = \frac{3}{2} X 20588,24 g/mol \\\\n H_2 = 30882.35 g /mol[/tex]
Then we can calculate the mass of hydrogen by multipy the moles with hydrogen molecular weight
[tex]mass H_2 = n XMW\\mass H_2 = 30882.35 g X2g/mol\\\\mass H_2 = 61764.7 g = 617.647 Kg[/tex]
Therefore, 617.647 Kg the hydrogen will be required to synthesize 350 kg ammonia
