What is the molar mass of ethanol? How many molecules of ethyl alcohol (C_2 H_6 O) are there in a bottle that has 275 ml of pure ethyl alcohol? The density of alcohol is 0.789 g/mL. Ethanol (the drinking alcohol), C2H5OH, has a density of 0.789 g/cm3. How many pounds of eth...
The molecular formula for ethanol is CH3CH2OH or C2H5OH. The shorthand formula is simply EtOH, which describes theethane backbonewitha hydroxyl group. The molecular formula describes the type and number of atoms of elements present in an ethanol molecule. Empirical Formula The empirical formula for ...

fruits and grains. It is often added to gasoline as an octane enhancer to form a fuel called gasahol. Ethanol’s formula is C 2 H 5 OH. This means each molecule of ethanol contains 2 C atoms, 6 H atoms, and 1 O atom. What is the mass percent of each element present in ethanol...
Calculate molality (m), in mol/kg, using the formula,Δt=Kf⋅m(Kf =3.9oC−kg/molfor lauric acid). Calculating Molality Molality can be defines as the moles of the solute per kilograms of the solvent. The molality of a solution is generally reporte...
10. Convert mass of ethanol to moles of ethanol; relate the moles of ethanol to the moles of ether produced using the stoichiometry of the balanced equation. Convert moles of ether to grams; divide the actual grams of ether (determined through the density) by the theoretical mass to ...
Calculate the molarity and mole fraction of acetone in a 1.29 m solution of acetone (CH_3COCH_3) in ethanol (C_2H_5OH). (Density of acetone = 0.788 g/cm^3; density of ethanol = 0.789 g/cm^3.) Assume t What is the solute in a solution made by mixing 10 mL of methan...
