A 1.37 M solution of citric acid (H3C6H5O7) in water has a density of 1.10 g/cm3 . Calculate the mass percent, molality, mole fraction, and normality of the citric acid. Citric acid has three acidic protons.
12 General Biology 101-004 John McDuffie- 2/10/17 Highlight = Example Highlight = Important Concept Highlight = Key Term - 4.4 Electron Configuration, Valence Electrons, and the Periodic Table - An atom’s outermost electrons (called valence electrons) are most important in determining the atom’s properties. - The electrons in all the sublevel s with the highest principal energy shell are called the valence electrons. - Electrons in lower energy shells are called core electrons. - One of the most important factors in the way an atom behaves, both chemically and physically, is the number of valence electrons. - Because quantum-mechanical orbitals fill sequentially with
