Hey richard, I had asked some chemist on Quora.com what the stoic is, the responded 11.4:1

His response:

Quote:

The combustion of isopropanol is:
C3H8O +9/2 O2 = 6CO2 +8 H2O
Mol weights are 60 for IP
32 for O2
So for each mole of IP burned,60g you need 9/2 of O2 that is 9*32/2=144g
ratio is 60/144 or 1:2.4
air is not 100% O2 is is only 21% so need
2.4/.21= 11.4

No wonder they were shooting flames.
