Answer: The new pressure is 831 mm Hg
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 740 mm Hg
= final pressure of gas = ?
= initial volume of gas = 2.2 L
= final volume of gas = 2.0 L
= initial temperature of gas = 290 K
= final temperature of gas = 296 K
Now put all the given values in the above equation, we get:
The new pressure is 831 mm Hg
Answer:
