The answer depents on the density of the substance involved. If the substance is water (density = 1) then 3.45 liters would have a mass of 3.45 kilograms. 1 kilogram = 2.2406 lbs so 3.45 kg = 7.61 lbs
convert to mol, (divide by molar mass) then multiply by 22.4
604 g
You need to redefine your question. A litre is a unit of volume and a kilogram is a unit of mass, so you have to know how densely compressed the hydrogen is before you can make a valid comparison of mass and volume. See Boyle's-Charles' Law.
A tonne of top soil is about 750 liters. Therefore 1600 liters is 2.13 tonnes

345 liters = 91.14 US gallons.
345 liters = 91.14 US gallons.
L = mL/1000.0 345/1000 = .345 Liters. Divide by 1000 = 0.345 L There are 1000 milliliters in 1 liter. One milliliter is 0.001 liter
1 litre = 1000 millilitres. 345 millilitres = 0.345 litres.
345 mL is 0.345 liters (1 liter = 1,000 mL).
The mass of 4.38 liters of oxygen is 6,259 g.
Offcurse mass is calculated in gram. Liters is the unit for volume
345 mm is a measure of length. A measure of density would have units of mass divided by volume.
No : liters is a unit for volume
i have tea sets dated 1900 from pathpoint mfg. new bedford mass. with the numbers on the bottom that say 345
345
You have to say what of? Pounds is (sort of) mass and liters is volume.
