Answer:

6.57 mL.

Explanation:

  • Boyle's law states that: at a constant temperature the pressure of a given mass of an ideal gas is inversely proportional to its volume.
  • It can be expressed as: P₁V₁ = P₂V₂,

P₁ = 64.4 kPa, V₁ = 9.66 mL.

P₂ = 94.6 kPa, V₂ = ??? mL.

∴ V₂ = (P₁V₁)/(P₂) = (64.4 kPa)(9.66 mL) / (94.6 kPa) = 6.57 mL.
