i think it is one british thermal unit
A gallon of jet fuel supplies 126,000 BTU. So...a million BTU is less than 8 gallons.
Propane = 91,600 btu per gallon
If there are 93,000 btu's per gallon of propane, and you are burning 25,000 per hour. That would be 3.72 hours per gallon or approx .27 gallons per hour. 6.45 gallons per day.
#2 fuel oil = 140,000 btu per gallon/10 =14000 btu X 2 =28000 btu
There is a total of 8 atoms in Ethane.
Recommend 400,000 BTU heater
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
You need to know eactly how many gallons and btu that require for your home.
About 0.43 US gallons of oil.
400k btu
mol. mass of ethane = 2x12.01+ 6x1.008= 30.01g/mol # of mole in 0.334 of ethane= 0.334/30.01= 0.01mol
