#V_2 = 141.09 mL#

This problem requires the use of Charles' Law comparing the direct relationship between Volume and Temperature.

#V_1/T_1 = V_2/T_2#

#V_1= 130 mL#
#T_1=20^oC = 293K#
#V_2=?#
#T_2=45^oC = 318K#

Always convert #^oC# to #K#

#K=^oC +273#

I prefer to isolate the variable before I plug in the values

#(V_1T_2)/T_1 = V_2#

#(130mL(318cancelK))/(293cancelK)= V_2#

#V_2 = 141.09 mL#
