First let us compute for the number of moles of butane (molar mass = 58.12 g/mol)

number of moles = 145 g / (58.12 g/mol) = 2.49 mol

We use the ideal gas equation to calculate the volume:

V = n R T / P

V = 2.49 mol * 62.36367 L torr / mol K * 308.15 K / 745 torr

V = 64.35 L

Jeff is certainly using a night vision goggle to see in the dark . It senses infrared radiations

Infrared radiations are part of the electromagnetic spectrum.
Every hot objects gives off infrared radiations.
These googles have thermal imaging sensors that detects these radiations.
Naked eyes cannot see the radiations.
The heat emitted is a form of radiation called the infrared radiation.
