Question

The volume of a gas with a certain mass is 10 L at STP. What will be the volume of this gas at 75 cm Hg and 27 °C ?

Answer 1

The volume of a gas with a certain mass is 10 L at STP.

To find : the volume of this gas at 75 cm Hg and 27°C

solution : at standard temperature and pressure,

temperature, T₁ = 273K ,

Pressure, P₁ = 76 cm Hg

volume, V₁ = 10L

final volume, V₂ = ?

temperature, T₂ = 27° C = 300K

pressure, P₂ = 75 cm Hg

using formula, P₁V₁/T₁ = P₂V₂/T₂

⇒76 × 10/273 = 75 × V₂/300

⇒760 × 300/(273 × 75) = V₂

⇒V₂ = 11.13 L

Therefore the volume of gas at 75 cm Hg and 27°C is 11.13 L .
