Well you know volume is V is proportional to T so:

V=kT -> V/T=k

Therefore since V/T is a constant,

Vinitial/Tinitial = Vfinal/Tfinal

so

350/298 = 155/T

so you get T = 132K, which is -141˚C

-
V/T=V1/T1


350. mL/25°C = 155 mL/T1

solve for T1

make sure to convert your temperature to kelvin first you might want to convert to liters also
heres another version

T1 =155 mL/350. mL/25°C

133K... it's a Charles' law problem
