Answer:

1067 mL

Explanation:

Considering that the temperature is constant,by Boyles law

P1V1 = P2V2

  • Subscript 1 refers intial
  • Subscript 2 refers final.
  • P1 = 457 mm Hg
  • P2 = 650 mm Hg
  • V1 = ?
  • V2 = 750 mL

Put in ;

457 * V1 = 650*750

Solve for V1

  • V1 = 650*750/457 =1066.73 = 1067 mL

Answer:

Using Boyle's law ( P_1 \cdot V_1 = P_2 \cdot V_2 ), we can find the initial volume ( V_1 ) with the given initial pressure ( P_1 ), final pressure ( P_2 ), and final volume ( V_2 ).

Plugging in the values:

( 457 \cdot V_1 = 650 \cdot 750)

Solving for ( V_1 ):

( V_1 ≈ 1066.07 ) mL

The closest option is c. 1100 mL.
