1.9L=1900mL=1900 cm 3
density=grams/ cm 3
grams= density * cm 3
x = .79g/cm3 * 1900cm3
x = 1501 grams
1lb = 453.59 grams
1501 grams / (453.59 grams/lb) = 3.31 lbs

you must convert liters from europe into a usa term like pints or gallons to match with pounds. PS white gas may have different weight properties. Gases may weigh less as the backpacker travels up a mountain. Gases may turn from a liquid state or a semi liquid state to a gas state depending on ambient temperature outside. The weight could change constantly.

Get the density of ‘white gas’
Find mass using that volume and the density
Convert mass to pounds

A gallon of any liquid weighs about 8 lbs. , so roughly 2 liters weighs about 3 and a half lbs.
