and 0.993 atm?
(5 Points)
22.1 mL
26.3 mL
2.2 mL

Answer : The final volume of gas will be, 26.3 mL

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

where,

= initial pressure of gas = 0.974 atm

= final pressure of gas = 0.993 atm

= initial volume of gas = 27.5 mL

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

Now put all the given values in the above equation, we get:

Therefore, the final volume of gas will be, 26.3 mL
