![**Problem Statement:**
A sample of gas occupies a volume of 66.2 mL. As it expands, it does 116.7 J of work on its surroundings at a constant pressure of 783 Torr. What is the final volume of the gas?
**Student Response:**
V = 113.14 mL
**Feedback:**
Incorrect
**Explanation:**
To find the final volume of the gas, you should use the work done by the gas at constant pressure, which can be calculated using the formula:
\[ \text{Work} = P \Delta V \]
where \( P \) is the pressure in pascals and \( \Delta V \) is the change in volume in cubic meters.
Remember that:
1 Torr = 133.322 pascal
1 mL = \( 1 \times 10^{-6} \) cubic meters
Convert the given data into the appropriate units and calculate the change in volume. Then use the initial volume to find the final volume. Make sure to check your calculations and units for accuracy to solve the problem correctly.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F8547315f-a2b1-4fb3-8610-7db5d0a7d9a2%2F65916555-739b-4280-8d41-66d803827a3a%2Fybu9nqp_processed.jpeg&w=3840&q=75)
