### Gases weights and volume

Posted: Sat Sep 12, 2009 3:30 am
Hi, I just found how to make a post. Why was it so difficult to find, It must be me but I've come across better. On a forum like this i thought it would be as visible as the Q's & A's.
My question. "Is it possible to assertain how much gas is left in a gas bottle by weighing it." e.g if the bottle is "full" when purchased and weighs X amount, is there a chart (or other way) which correlates the weight to volume or more basically to approximate how long more the gas might last. I appreciate with all the variables it's can't a linear figure but maybe someone has tried to estimate it. God Bless. Cristo

How can I determine the speed of a vehical travelling at 22 metres in 3 seconds; what would the speed of the vehicle be per hour.

You may not be able to help me, but please can you advise.
