Answer: 
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 = 101.3 kPa
= final pressure of gas = 94.6 kPa
= initial volume of gas = 20.0 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 the final volume of gas.
Thus the correct numerical setup for calculating the new volume is
