What isdensity of LPG in Kg/M3

Can anybody tell me what is the density of LPG

It depends on the type and form. If it is liquid butane it will be 570-580 kg/m3, however if it is gas it will be 1.9-2.1 kg/m3. Liquid propane will be 500-510 kg/m3, and propane gas will be 1.4-1.55 kg/m3. Hope this helps.

It depends on the form of LPG you are using.If it is in gaseous form then the density is 2.155kg/cubic meter,if its in liquid form then 553 kg/cubic meter.

I am using piped LPG cooking gas.

The company has submitted its first bill and given consumption in M3 and billed me in Kg consumed.

Would anybody tell me the conversion rate M2 to Kg for Cooking LPG?

There are two problems with giving you a good answer:
*The volume of a gas is meaningless, unless the pressure and temperature at which it is measured are also stated. Meters may indicate the volume at some standard reference condition regardless of actual. But we need the conditions.

*In the US and Canada, it is at least 95% propane, and there is little error from using propane data. In much of the rest of the world, it is a mixture of butance and propane; the ratio is needed to calculate density.

Having said all that, for the US, at 15 °C, 101.325 kPa, 1.9 kg/m³ is a good approximate density. A 50/50 propane/butane mix might be 2.2 kg/m³

Pl convert the following gasses into kg

lpg:835nm3
oxygen:19355nm3
nitrogen:4855nm3
argon:235nm3

At "normal" conditions. 22.414L is 1 mole, or 22.414 m³ = 1 kmol. Reduce each gas to an amount in moles.

Now compute the molecular weight of each gas. That weight in grams is also a mol (or kilograms a kilomole)
Doing oxygen as an example
19355 Nm³ X 1 kmol/22.414 m³ x 32 kg/kmol = 27633 kg

Its depends on the temperature!! on 30degrees it can be arround 0.5696 somthing!

whats the ratio of butane and propane in lpg (2.155kg/cubic meter).

Sir if the LPG meter is of 0.2 bar and is given in M3 the how to find the density in kg/m3?
