A sample of gas occupies a volume of 73.7 mL. As it expands, it does 133.7 J of work on its surroundings at a constant pressure of 783 torr. What is the final volume of the gas?

A (S) + B (S) = C (g)

A (g) + B (g) = 3C (g)

A (g) + B (g) = C (g)

A (s) + 2B (g) = C (g)

A sample of gas occupies a volume of 73.7 mL. As it expands, it does 133.7 J of work on its surroundings at a constant pressure of 783 torr. What is the final volume of the gas?

A (S) + B (S) = C (g)

A (g) + B (g) = 3C (g)

A (g) + B (g) = C (g)

A (s) + 2B (g) = C (g)

In thermodynamics, work performed by a system is the energy transferred by the system to its surroundings. It can be calculated by the expression:

W = PdV

Integrating,

We will have,

W = P (V2 - V1)

133.7 (1 litre-atm / 101.325 Joule) (760 Torr / atm) = 783 (V2 -.0737)

V2 = 1.35 L

Hope this answers the question. Have a nice day.
