Answer:

#V_2=254.6 mL#

Explanation:

For this question we would use Boyle's equation for the relationship between Pressure and Volume

#P_1V_1=P_2V_2#

#P_1 = 645mmHg#
#V_1=300mL#
#P_2=1atm = 760mmHg#
#V_2=?#

#645mmHg(300mL)=760mmHg(V_2)#

#(645cancel(mmHg)(300mL))/(760cancel(mmHg))=(cancel(760mmHg)(V_2))/(cancel(760mmHg))#

#254.6 mL = V_2#
