Q10) Describe spectrophotometry tests? If you were given a solution that contains an absorbing molecule how would you determine its max absorbance?

For light with a wavelength of 6.70 µum, calculate the corresponding wavenumber value. wavenumber cm -1

Sketch the form of an A2M2X3 spectrum, where A, M, and X are protons with distinctivelydifferent chemical shifts, and JAM > JAX> JMX. What is the total number of lines in thespectrum?

Suppose you are analyzing mercury ions (Hg2+) in drinking water samples with atomic absorption spectroscopy. If the Hg2+ signal varies by a matrix of sample, which of the following should be used as a standard for calibration? Either cations or anions can be used if they are different from Hg2+, 0 H20 Any anions can be used if they are different from Hg2+ Any cations can be used if they are different from Hg?". Hg2+

Identify the spectra. All pertinent peaks must be assigned on spectrum (5-6 peaks). Label the peaks on spectrum.  I have provided the correct structure in the lower left hand corner, I just need help with labeling the peaks on the spectrum to match the structure.

A solution with a known concentration equal to 3.4 mM gave an absorbance reading of 0.820 in a spectrophotometer. Assuming that there is a linear relationship between concentration and absorbance up to a concentration of 4.0 mM, what would the absorbance reading be for a solution with a concentration 2.2 mM?

If two signals differ by 1.5 ppm in a 300 MHz spectrometer, by how much do they differ in a 500 MHz spectrometer?
