The pressure on 100 cm³ of oxygen gas at 35°C is 750mm of Hg.What would be the volume of the gas if the pressure is increased to 1000mm of Hg without changing the temperature?

133.3 cm³

85 cm³

75 cm³

65 cm³

58.3 cm³

Correct answer is C

P₁ = 750MHg V₁ = 100cm³ l₂ = 308k
P₂ = 100 mmHg V₂ = ?
But (P₁V₁)/(T₁) = ((P₂V₂)/(T₂) i.e (750 x 100)/(308) = (1000 x )/(V₂)/(308)
V₂ = (750 x 1000 x 308)/(308 x 1000) = 75 cm³
