The compound that gives the given mass spectrum has to be determined. Concept Introduction: Mass spectrometry: It is a technique used to find out the molecular weight of the compounds and thus providing the structure and chemical properties of different molecules. The sample ion is converted into gaseous ions with or without fragmentation and are characterized by their charge to mass ratios and relative abundances. Mass spectrum is a plot of the relative abundance of the generated ions as a function of the charge to mass ratio. Molecular ion peak (M) + • : It is defined as the heaviest peak in the mass spectrum of the molecule which represents the largest molecular ion in the given molecule with greater m/z value. Base peak: It is the tallest peak in the spectrum. The (M+1) + • peak: It denotes the peak that arises next to molecular ion peak in the mass spectrum. The peak arises due to the presence of the isotope of carbon ( 13 C ) .

Interpretation:

The compound that gives the given mass spectrum has to be determined.

Concept Introduction:

Mass spectrometry:

It is a technique used to find out the molecular weight of the compounds and thus providing the structure and chemical properties of different molecules.

The sample ion is converted into gaseous ions with or without fragmentation and are characterized by their charge to mass ratios and relative abundances.

Mass spectrum is a plot of the relative abundance of the generated ions as a function of the charge to mass ratio.

Molecular ion peak(M)+•: It is defined as the heaviest peak in the mass spectrum of the molecule which represents the largest molecular ion in the given molecule with greater m/z value.

Base peak: It is the tallest peak in the spectrum.

The (M+1)+• peak: It denotes the peak that arises next to molecular ion peak in the mass spectrum. The peak arises due to the presence of the isotope of carbon (13C).

4. Draw and label all possible isomers for [M(py)3(DMSO)2(CI)] (py = pyridine, DMSO dimethylsulfoxide).

The emission data in cps displayed in Table 1 is reported to two decimal places by the chemist. However, the instrument output is shown in Table 2. Table 2. Iron emission from ICP-AES Sample Blank Standard Emission, cps 579.503252562 9308340.13122 Unknown Sample 343.232365741 Did the chemist make the correct choice in how they choose to display the data up in Table 1? Choose the best explanation from the choices below. No. Since the instrument calculates 12 digits for all values, they should all be kept and not truncated. Doing so would eliminate significant information. No. Since the instrument calculates 5 decimal places for the standard, all of the values should be limited to the same number. The other decimal places are not significant for the blank and unknown sample. Yes. The way Saman made the standards was limited by the 250-mL volumetric flask. This glassware can report values to 2 decimal places, and this establishes our number of significant figures. Yes. Instrumental data…
