Answer:
V₂ = 155.17 mL
Explanation:
Given data:
Initial volume = 150 mL
Initial pressure = 0.587 atm
Initial temperature = 155 K
Final temperature = 273.15 K
Final volume = ?
Final pressure = 1 atm
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
V₂ = P₁V₁ T₂/ T₁ P₂
V₂ = 0.587 atm × 150 mL × 273.15 K / 155 K × 1 atm
V₂ = 24050.86 atm .mL. K / 155 K.atm
V₂ = 155.17 mL
Answer: 0.428%
Explanation: % Error = [(measured - Actual)/Actual]*100%
(93.9g - 93.5 g)/93.5g = 0.428%
