gas calculations
I'm new to figuring out gas calculations and wanted to check to make sure I did it right.
LiAlH4 + 4 H2O ===> LiOH + Al(OH)3 + 4 H2
100 mgs. LiAlH4 = .00263 moles
.00263 x 4 = .0105 moles H2
.0105 moles H2 @ 22.4 litres / mol = .235 L (235 ml)
(293K / 273K ) x 235ml = 252 ml @ 20C
20 mgs. LAH ~ 50 ml H2 @ 20C

The single most important condition for a successful synthesis is good mixing - Nicodem

I thought STP meant 25 C ?

For IUPAC STP is 0C, for NIST it is 20C.
Two standards, ain't that always the way?
