The element lithium consists of two naturally occurring isotopes with relative abundances of 7.42% and 92.58%. The atomic mass of one of these isotopes is 6.0135. Determine the atomic mass of the other isotope.
how could you use IR spectroscopy to identify which alkene is in which vial? How do you determine what the wavenumber values are for specific compounds/ elements?
The Henderson-Hasselbalch equation is used to calculate the pH of a weak base, but not the pH of a weak acid.
