Answer:
14.45g
Explanation:
We have a balanced equation:
3H2(g) + N2(g) → 2NH3(g)
We know the mass H2 = 2.55g
We can work out the moles of H2 - Mass = mr x moles
Moles = mass/ mr = 2.55/ 2 = 51/40
Using the ratios in the question, this is 3:2
51/40 /2 x 3 = 17/20
so there are 17/20 moles NH3
Mass = mr x moles = 17/20 x 17 = 289/20 = 14.45g
Hope this helps! Let me know if you have any questions :)
