Answer:

#0.25 atm#

Explanation:

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#
