What is the final volume of 725 mL of neon gas at 240.°C if the gas is cooled to 54.5°C? Assume the pressure and the amount of gas are held constant.

v1 725/100 = .725
v2  unknown
t1 240 C +273 K (to convert celcius to kelvin
t2  54.5 C + 273 K
V2 = .725 x 327.5 / 513
v2 = .462841
V2= .46 
v1 725/100 = .725
should be 725/1000; otherwise ok through the problem. At the end, V2 should be rounded to 0.463 and the unit should be L. 
yep forgot the units sorry.
