$0.25 atm$

The formula below will be used as a reference:

Identify the known and unknown variables.

$color(red)("Knowns:"$
$P_1$ = 1.00 atm
$V_1$ = 0.5 L
$V_2$ = 2.0 L

$color(maroon)("Unknowns:"$
$P_2$

Rearrange the equation to solve for the final pressure by dividing both sides by $V_2$ to get $P_2$ by itself like this:

$P_2=(P_1xxV_1)/V_2$

Plug in your given values to obtain the final pressure:

$P_2=(1.00\atm xx 0.5\ cancel"L")/(2.0\cancel"L")$ = $0.25 atm$
