Answer:
V₂ = 626.52 mL
Explanation:
Given data:
Initial volume = 268 mL
Initial temperature = 151 K
Final temperature = 353 K
Final volume = ?
Solution:
V₁ / T₁ = V₂ / T₂
V₂ = V₁ T₂/ T₁
V₂ = 268 mL× 353 K / 151 K
V₂ = 94604 mL.K / 151 K
V₂ = 626.52 mL
PH = -log[H+]
pH = -log[1,7×10^-9]
pH = 8,77
pH + pOH = 14
pOH = 14 - 8,77
pOH = 5,23
