How do you covert pounds of liquid oxygen into liters?

Answer 1

Liquid oxygen is measured in pounds and gaseous oxygen in liters. So the quickest method would be to ignite it.

Just kidding. :-)

If you know the mass of something (for example, by being given its weight in pounds at "one g") and you want to know its volume (for example, in liters), then you need to also know the density, and that:

density = mass divided by volume

which you can solve for

volume = mass divided by density

The density of liquid oxygen at various temperatures and pressures you can look up. An "I'm feeling lucky" search for density of liquid oxygen at Google takes you to

http://www-safety.deas.harvard.edu/services/oxygen.html

which gives the density at boiling point at one atmosphere as

Density, Liquid @ BP, 1 atm: 71.23 lb/scf

Then Google for 1 cubic foot in liters to get

1 (cubic foot) = 28.3168466 liters

Answer 2

Convert pounds to grams. GET TO METRIC. Then using the density of liquid oxygen, divide the original grams by the grams in the density. Then, you should be able to get this, convert millilitres into litres. TADA

Answer 3

liters to pounds can't do it completely accurate but if its a liquid than you have to measure it in liquid forms... liters, gallons etc
