you divide 71.5 by 2
Explanation:
it's may look intimidating but the question is actually really simple.
The correct answer is: [B]:
___________________________________________________________
" N₂ (g) + 3 H₂ (g) → 2 NH₃ <span>(g) " .

G about the answer if I don’t do this I Will fail!!!!!! NO LINKS NO LYING
1) number of moles of N2 = n/2
2) Number of moles of CH4 = n/2
3) Total number of moles of the mixture = n/2 + n/2 = n
4) Kg of N2
mass in grams = number of moles * molar mass
molar mass of N2 = 2 * 14.0 g/mol = 28 g/mol
=> mass of N2 in grams = (n/2) * 28 = 14n
mass of N2 in Kg = mass of N2 in grams * [1 kg / 1000g] = 14n/1000 kg = 0.014n kg
Answer: mass of N2 in kg = 0.014n kg
