For this you need the atomic (molecular) mass of C2H5OH. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel. C2H5OH= 46.1 grams1.271 grams C2H5OH / (46.1 grams) = .0276 moles C2H5OH


Ethanol is a compound. Its molecular formula is C2H5OH.


This is a Tetrahedral on each of the C's because there are no unpaired electrons.


C2H6O is the formula for ethanol. More Commonly known as..C2H5OH


The structural formula is CH3CH2OH. The molecular formula is C2H5OH. (not C2H6O)


It's a molecular compound since none of the elements involved are metals. Also it is a base due to the OH bond.


I assume you mean the molecular mass. Its molecular mass is 342.3g/mol


The reaction equation is: C2H5OH + 3 O2 = 2 CO2 + 3 H2O. Therefore, the ratio of moles of O2 to moles of C2H5OH is 3, and 3 X 1.3 = 3.9 moles of O2 are required. The molecular mass of O2 is about 32, so that 3.9 X 32 = 125 grams of oxygen.
