Not all natural gas [1] is the same, as a result it is hard to come up with precise number for the density of natural gas at any one specific temperature.

With this said as an approximate value you can assume that its density relative to air is a constant, at least at normal atmospheric pressures. As a result you could use is specific gravity relative to air of 0.585 [1]

Alternately, since Natural gas is mainly Methane (87-96%) [1] you could us the density of Methane [2] as your density. The ASTM standard would allow you to make PVT estimates at a range of pressures and temperatures.

In both cases these would be approximations, but may be close enough for your application.

How precise an estimate do you need?
