Explanation:
2.5 M = 2.5 mol/L
2.5 mol/L * 4 L = 10. mol
1st one is E
2nd one is also E
Answer:
<h2>7.54 atm </h2>
Explanation:
The required pressure can be found by using the formula for Boyle's law which is

where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
From the question we have

We have the final answer as
<h3>7.54 atm </h3>
Hope this helps you
