Asample 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

c. is the answer
