Answer:
This is what we're given:
V
1
, or initial volume, which is
2.5 L
.
P
1
, or initial pressure, which is
1.5 atm
.
P
2
, or final pressure, which is
1 atm
.
We have to find
V
2
, or the final volume.
Boyle's law actually relates all four of these variables!:
P
1
V
1
=
P
2
V
2
This equation can be rearranged to have only
V
2
on one side:
V
2
=
P
1
V
1
P
2
Now, we just need to plug in all of the variables to find
V
2
:
V
2
=
1.5 atm × 2.5 L
1 atm
V
2
=
1.5
atm
×
2.5 L
1
atm
V
2
=
3.75 L
