Volume = 2.7 mol/3.0 L
Volume = 0.9 L
Answer:
1
Explanation:
4 HBr + O2 → 2H 20 + 2Br 2
...............
V₁ = initial Volume of the balloon after it is blown up = 365 L
V₂ = new Volume of the balloon after it is taken outside = ?
T₁ = initial temperature of the balloon = 283 K
T₂ = new temperature of the balloon = 300 K
using the equation
V₁/V₂ = T₁/T₂
365/V₂ = 283/300
V₂ = 387 L
