For an ideal gas:
pV = nRT
p = pressure in Pascal (Pa)
V = volume in cubic meters (m3)
n = amount of substance in moles (mol)
R = the molar gas constant (8.31446261815324 J⋅K−1⋅mol−1)
T = temperature in Kelvin (K)
With 1 L = 10-3 m3 and 1 kPa = 103 Pa, 1 kPa*L = 1 Pa*m3
T = pV / (nR), put in the numbers, and you'll get your answer. (It's cold!)
