a sample of a gas occupies 1.40 x 10^3 mL at 25°C and 760 mmHg. what volume will it occupy at the same temperature and 380 mmHg

The volume that the gas will occupy at the same temperature is

2800 Ml

calculation

This volume is calculated using Boyle's law formula since the temperature is constant

that is P₁V₁=P₂V₂ where,

P₁ = 760 mm hg

V₁ = 1.40 x 10³ ml

P₂ = 380 mmhg

V₂ = ? ml

make V₂ the subject of the formula by diving both side of equation by P₂

V₂ = P₁V₁ / P₂

V₂ = [760 mmhg (1.40 x 10³) / 380 mmhg] = 2800 ml
