A gas occupies a volume of 0.35 dm ^3 at 290 K and 2 atm. Pressure. Calculate the volume of gas at STP.

Options

A3.11 dm ^3
B0.66 dm ^3
C0.11 dm ^3
D3.5 dm ^3

Correct answer

B. 0.66 dm ^3

Step-by-step solution

Using the combined gas equation: P₁ V₁ T₁ = P₂ V₂ T₂ Given: P₁ = 2 atm V₁ = 0.35 dm ^3 T₁ = 290 K At STP: P₂ = 1 atm T₂ = 273 K Substituting the values: 2 0.35 290 = 1 V₂ 273 V₂ = 2 0.35 273 290 V₂ = 191.1 290 0.66 dm ^3 Answer: 0.66 dm ^3
