What Is the Resistivity of Pure Steam?

[assume]

I am working on a Project that involves determination of Quality of Steam. In that I have few queries, so please help if possible:

1. Is there any mathematical relationship between Resistivity of water and temperature? because i am not able to find one, but since i am working on this project, so by doing practical I found that: Resistivity of water decreases with increase in temperature, but I am not able to find any mathematical relationship?

2.What is the resistivity of pure steam?
I read on the net, that steam has infinite resistance, but infinite does not exist so there must be some value ( may be in Mega ohm, giga ohm, etc); I am looking for that value?

Thanks.
