What is the mole fraction of ethanol in a solution of 47.5 grams of ethanol in 85 grams of water? What is the mole fraction of ethanol,C_2H_5OH, in an aqueous solution that is 50.0% ethanol by mass? What is the mole fraction of ethanol, C2H...
Glacial acetic acid can be described as the concentrated form of acetic acid. Acetic acid is an organic compound having the chemical formula CH3COOH. Therefore, the molar mass of this compound is 60 g/mol, while the IUPAC name of this compound is Ethanoic acid. Moreover, at room temperature...
These are much weaker than the chemical bonds but are essential in determining the overall property of the compound. For instance, the fact that water has a higher boiling point than methanol even though methanol has a higher molar mass is explained by the IMFA present....
