Molar mass of ethanol is: 46 grams/moles
C2H6O-> 2x12 + 6x1+ 16x1 (see periodic table)
If 46 g correspond to 1 mol, how much moles correspond 35 g?
46g ====1mol
35g====x
x= 35/46
x=0,76 mol
-1367 kj/mol, means that there are -1367 kj in one mol
1mol ==== -1367 kj
0,76mol==== x
x=- 1040Kj
Ethanol released 1040 Kj.
3-ethyl-2.4-dimethyl-octanoic acid
Answer:
because the water brings a cool breeze when the wind blows
Explanation:
Volume has the same relationship with the number of particles than the pressure.
You can see it in the ideal gas equation: PV = nRT
As much as V and P are proportional to n.
Use of the empirical formula
