Answer:

The new Pressure would be #3.125 atm#

Explanation:

In order to solve this problem we will use Boyle's Law which is the relationship between Pressure and Volume at a fixed temperature.

The equation is #P_1V_1=P_2V_2#

#P_1 = 1atm#
#V_1 = 250 mL#
#P_2=?#
#V_2=80mL#

#(1atm)(250mL)=P_2(80mL)#

#((1atm)(250cancel(mL)))/(80cancel(mL))=(P_2(cancel(80mL)))/(cancel(80mL))#

#3.125 atm = P_2#
