Question

175 mL of Cl2 gas is held in a flexible vessel at

STP. If the vessel is transported to the bottom of
the impact basin Hellas Planitia on the surface of
Mars where the pressure is 1.16 kPa and the
temperature is -5 °C, what is the new volume of
Cl2 in liters?
- L

Answer 1

Answer: its 15.0 L

Explanation: trust me

Answer 2

V₂ = 15.6 L

Step-by-step explanation:

Given data:

Initial volume = 175 mL (0.175 L)

Initial pressure = 1 atm

Initial temperature = 273 K

Final temperature = -5°C (-5+273 = 268 K)

Final volume = ?

Final pressure = 1.16 kpa (1.16/101=0.011 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 = 1 atm × 0.175 L × 268 K / 273 K × 0.011 atm

V₂ = 46.9 L / 3.003

V₂ = 15.6 L
