About a kilogram.
Nm3 is a measure for volume of gases, in cubic meter, under special conditions of pressure (1 atm) and temperature ( zero degrees centigrade). The name for this unity is Normal Cubic Meter. It is not Newton meter cubed.
Conversion factor depends on various factors like composition of the LPG, temperature, molecular weight and so many others.Following are the conversion factors just for rough calculations.One kg of liquid Propane when converted to vapour (at 15.56 degrees centigrade temperature) will be equal to 0.539 Cubic Meter.One kg of liquid Butane when converted to vapour (at 15.5 degrees centigrade temperature) will be equal to 0.410 Cubic Meter.One kg of liquid LPG (70:30) when converted to vapour (at 15.5 degrees centigrade temperature) will be equal to 0.449 Cubic Meter.OR45kg LPG = 20.20 Cu. Meter vapour. Or for 45kg Propane = 24.26 Cu. Meter of vapour.As a thumb rule Liquid Propane expands to 270 times and Butane to 235 times into vapour when released into air.
As the density of Oxygen at 0º C is 1.429 kg/m³ i.e. cubic meters * density = kilograms so, 1 cubic meter of oxygen would weigh 1.429 kilograms.
At 25 degrees Celsius the density of fresh water is 997.04 kilograms per cubic meter or 0.99704 grams per cubic centimeter. The mass m = 0.8 cubic meter times 997.04 kilograms per cubic meter = 797.632 kilograms.
The density of fresh water at 17 degrees Celsius is 998.77 kilograms per cubic meter. The density of fresh water at 19 degrees Celsius is 998.40 kilograms per cubic meter.

It could way less, it could way more, or it could way the same. Depends on the pressure. If the pressure is the same in both cubic meters, then the hydrogen ways less than the oxygen.
Water has a density of 1 gram per cubic centimeter. There are 1,000,000 cubic centimeters in a cubic meter, so 1 cubic meter has a mass of 1000 kilograms.

Kilogram per cubic meter is the one that doesn't belong. Square meter is meter^2 and cubic meter is meter^3 but kilogram per cubic meter is a density
