How much energy (in kj) is released when 26.3 g of nh3 is formed?

Energy released:

Explanation:

In Haber's process Ammonia formation takes place according to equation:

According to this equation ,when 2 mole of ammonia is formed from 3 mole of nitrogen and 1 mole of oxygen  then 92 kJ of heat is released.

1 mole of contains 17.03 g

mass of N=14.0067 g/mol

mass of H=1.007 g/mol

mass of =14.0067+3.021

mass of =17.03 g/mol

So, 2 mole of contains=34.06g

Since 34.06g (or 2mol) = -92 kJ

this gives

Hence amount of energy released when 26.3g of ammonia is formed is -71.03 kJ

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
