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
