Question

n₂(g) + 3h₂(g) → 2nh₃(g)
how many liters of nh₃ is produced from 82 l of h₂ at stp?
? l nh₃

Explanation:

Step1: Relate H₂ and NH₃ volumes

At STP, gas volumes ratio = mole ratio. From reaction: 3 L H₂ → 2 L NH₃.
Volume of NH₃ = Volume of H₂ × $\frac{2}{3}$

Step2: Calculate NH₃ volume

Substitute H₂ volume (82 L):
$82 \times \frac{2}{3} \approx 54.67$

Answer:

55 (rounded to nearest whole number) or 54.7 (rounded to one decimal place)
