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 -5.0°C. What is the new
volume of Cl2 gas in liters?

Answer 1

Answer:

Explanation:

We shall apply formula of gas laws

P₁V₁ / T₁ = P₂V₂ / T₂

P₁ , V₁ , T₁ are at STP  and P₂ , V₂ , T₂ are pressure ,volume and temperature at Mars

P₁ is atmospheric pressure = 10⁵ Pa , st temperature = 273

Putting the given values in the formula

10⁵ x 175 / 273 = 1.16 x 10³ x V₂ / (273 - 5)

V₂ = 10⁵ x 175 x268 / 273 x 1.16 x 10³

= 14810 mL.
