Answer:
P₂ = 1.4 atm
Explanation:
Given data:
Initial volume = 775 mL
Initial pressure =1 atm
Initial temperature = 273 K
Final temperature = 25°C (25+273 = 298 K)
Final volume = 615 mL
Final pressure = ?
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 1 atm. 775 mL . 298 K / 273 K. 615 mL
P₂ = 230950 atm / 167895
P₂ = 1.4 atm
