✔ 最佳答案
At original conditions: P₁ = 7.80 × 10² torr, V₁ = 64.1 mL, T₁ = (273 + 25) K = 298 KAt STP: P₂ = P₁ = 7.60 × 10² torr, V₂ = ? mL, T2 = 273 K
For a fixed amount of gas : P₁V₁/T₁ = P₂V₂/T₂
Then: V₂ = V₁ × (P₁/P₂) × (T₂/T₁)
The volume of methane at STP, V₂
= 64.1 × [(7.80 × 10²)/(7.60 × 10²)] × (273/298) mL
= 60.3 mL
