Explanation:
Answer: There will be 0.00002 meq per Liter of the solution.
Explanation:
Normality is defined as the umber of gram equivalents dissolved per liter of the solution.
Equivalent weight is calculated by dividing the molecular weight by n factor.
n= charge for charged species , For
, n =2
Thus there will be 0.00002 meq per Liter of the solution.
Answer:
a) No. of moles of hydrogen needed = 5.4 mol
b) Grams of ammonia produced = 27.2 g
Explanation:

a)
No. of moles of nitrogen = 1.80 mol
1 mole of nitrogen reacts with 3 moles of hydrogen
1.80 moles of nitrogen will react with
= 1.80 × 3 = 5.4 moles of hydrogen
b)
No. of moles of hydrogen = 2.4 mol
It is given that nitrogen is present in sufficient amount.
3 moles of hydrogen produce 2 moles of 
2.4 moles of hydrogen will produce
= 
Molar mass of ammonia = 17 g/mol
Mass in gram = No. of moles × Molar mass
Mass of ammonia in g = 1.6 × 17
= 27.2 g
