Final answer:
To convert the volume at a different pressure to its new volume at standard pressure, use Boyle's Law. Substituting the given values into the equation, the new volume at standard pressure is 343.42 mL.
Step-by-step explanation:
To convert the volume at a different pressure to its new volume at standard pressure, we can use Boyle's Law. Boyle's Law states that the pressure and volume of a gas are inversely proportional at constant temperature.
We can use the equation:
P1V1 = P2V2
Where P1 and V1 represent the initial pressure and volume, and P2 and V2 represent the new pressure and volume. Rearranging the equation, we get:
V2 = (P1V1) / P2
Substituting the given values into the equation, we have:
V2 = (740.0 mmHg * 350.0 mL) / (760.0 mmHg)
V2 = 343.42 mL
Therefore, the new volume at standard pressure is 343.42 mL.
