Answer» Answer: CHEMISTRY avatar Asked on December 20, 2019 by Sumon Abhista Calculate the volume of ammonia gas produced at STP when 140 g of nitrogen gas reacts with 30 g hydrogen gas. (Atomic MASS: N=14 u, H=1 u) HELP best friend Study later ANSWER N 2
+3H 2
⟶2NH 3
Number of MOLES of N 2
in 140G= 28 140g
=5 moles of N 2
Number of moles of H 2
in 30g= 2 30
=15 moles of H 2
moles N 2
+3H 2
⟶2NH 3
at t=0 5 15 - after reaction 5−5×1 15−3×5 2×5 Thus 10 moles of NH 3
produced after reaction as number of moles= volume at STP volume of product
⇒10= 22.4L V
⇒V=224L Thus 224L of ammonia is produced. |
