1.	At 15°C and 900 mm pressure, 0.4 gram of a certain gas occupied 3280 mL. If the pressure is changed to 1300 mm at constant temperature. What is the density of the gas?
Answer» 1.762 × 10⁻⁴ g / mLExplanation:We know : Density = Mass / VOLUME= > Density at 900 mm PRESSURE = 0.5 / 3280 g / mL = 0.000122 g / mLAt constant temperature : = > Density × Pressured₁ / P₁ = d₂ / P₂= > d₂ = ( d₁ P₂ ) / P₁We have VALUES of : d₁ = 0.00012 g / mLP₁ = 900 mmP₂ = 1300 mmPutting values in d₂ : d₂ = ( 0.000122 × 1300 ) / 900 = > d₂ = ( 0.000122 × 13 ) / 9= > d₂ = 0.0001762 g / mL= > d₂ = 1.762 × 10⁻⁴ g / mLHence we get required ANSWER.
