Expert Solution
Step 1
The final volume of the gas can be measured by using the combined gas law. The combined gas law is:
Where
P1 = initial pressure of gas = 742 torr
V1 = initial volume of gas = 2.89 L
T1 = initial temperature of gas = 23.6oC = 23.6oC +273.15 = 296.75 K
P2 = final pressure of gas = 767 torr
V2 = final volume of gas = ?
T2 = final temperature of gas = 370.3oC = 370.3oC +273.15 = 643.45 K
