A sample of gas occupies a volume of 61.5 mL . As it expands, it does 130.1 J of work on its surroundings at a constant pressure of 783 Torr . What is the final volume of the gas? g

the final volume of the gas is = 1311.5 mL

Explanation:

Given that:

a sample gas has an initial volume of 61.5 mL

The workdone = 130.1 J

Pressure = 783 torr

The objective is to determine the final volume of the gas.

Since the process does 130.1 J of work on its surroundings at a constant pressure of 783 Torr. Then, the pressure is external.

Converting the external pressure to atm ; we have

External Pressure :

The workdone W = V

The change in volume ΔV=

ΔV =

ΔV =

ΔV = 1.25 L

ΔV = 1250 mL

Recall that the initial  volume = 61.5 mL

The change in volume V is

multiply through by (-), we have:

=  1250 mL + 61.5 mL

= 1311.5 mL

∴ the final volume of the gas is = 1311.5 mL

the answer is b & c i believe : )
