help needed with a few gas laws problems
« on: February 03, 2007, 09:02:26 AM »
My lab  partner and I have been trying to figure out a few problems we got on homeowork,  but so far have had absolutely 0 luck with understanding what we are supposed to do and completing the problems. here they are. any help would be greatly appreciated.

1.the Hindenburg was a hydrogen gas filled dirigible that exploded in 1937. if the Hindenburg held 2.0 X 10^5 m^3 of hydrogen gas at 23 degrees C and 1.0 atm, what mass of hydrogen was present.

2. suppose you are given two 1 L flask and told they one contains a gas of molar mass 30 , the other a gas of molar mass 60, both a the same temperature. he pressure in flask A is X atm, and the mass of the gas is 1.2 g. The pressure in flask B is .5X at, and the mass is 1.2 g. which flask contains gas of malr mass 30 and which contains the gas of molar mass 60.

thanks a ton for the help. these questions have had us stumped for days

The Hindenburg took 34 seconds to be entirely engulfed in flames. I guess some would say that was an explosion. In any case the implication that hydrogen was the cause of the speed of conflagration is appropriate.

By the way, it appears that you did not read the rules and I dare not respond lest I be chided for helping those who do not.

Please read forum rules.

What gas laws do you know? Which do you think should be used?

The original poster did not return.
Oh well!
