Answer: 196.68 mL
Step-by-step explanation:
Using Boyle's law:P1V1 = P2V2where P1 and V1 are the initial pressure and volume, and P2 and V2 are the final pressure and volume.Plugging in the given values:785 mmHg x 246.2 mL = 981 mmHg x V2V2 = (785 mmHg x 246.2 mL) / 981 mmHgV2 = 196.68 mLTherefore, the volume of the gas when its pressure is increased to 981 mmHg is approximately 196.68 mL.
